Answer:
6, 8 and 10 and -2, 0, 2
There are two roots x = -2 and 6,
but the since I don't believe 0 is an even number the answer is 6, 8 and 10
I was incorrect according to G0ggle zero is an even number so another answer is -2, 0, 2
Step-by-step explanation:
read the question and convert the English to mathematics
x, y and z even consecutive number
y = x+2
z = y+2 = x+4
and
xyz = x³ + y² + 2z² substitiute x terms in for y and z
x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solve for x by graphing on DEMOS
x = -2, 6 solved algebraically below
x = -2 y=0 z=2
x = 6 y=8 z=10
Checked both answers
xyz = x³ + y² + 2z²
-2(0)2 = -8 + 0 + 8 when x = -2
0 = 0
and
6(8)(10) = 6³ + 8² +2(10)² when x = 6
480 = 216+64+200
= 480
x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solved algebraically
(x²+2x)(x+4) = x³ + x² +4x +4 + 2x² + 16x + 32
x³ + 6x² + 8x = x³ + x² +4x +4 + 2x² + 16x + 32
x³ + 6x² + 8x = x³ + 3x² + 20x + 36
3x² - 12x - 36 = 0 factor out the 3
3[x² - 4x - 12] = 0
3(x+2)(x-6) = 0 x = -2 and -12

Answer:
I believe the circumference is 37.699
HOPE I HELPED!
PLEASE GIVE BRAINLIEST!
Step-by-step explanation:
Answer:
37.68 cm
Step-by-step explanation:
The photo shows the diameter as 12cm
The formula for the circumference of a circle is [tex]2\pi r[/tex]
If the diameter is 12, the radius is 6
[tex]2 \pi 6[/tex] = 2 x 3.14 x 6 = 37.68

Answer:
Median is the middle line of the box, Lower quartile is the number of the lower end of the box, Upper quartile is the line at the larger end of the box, Maximum is the largest number in the box plot (end of right whisker), Minimum is the lowest number (end of left whisker).
Step-by-step explanation:
32.
Median: 88
Maximum (largest number): 102
Minimum (lowest number): 38
Interquartile range:
96 - 72 = 24
b.
25 % higher
75 % lower?
c.
You can see the range is more towards the right of the box meaning they have higher scores, and that the median or middle is a higher number so it means that most of the students understood and did well on the test.

A small company has a fleet of 3 pickup trucks and 4 delivery vans. A larger company has the same ratio of pickup trucks to delivery vans. If the larger company has 45 pickup trucks, how many delivery vans does it have?
Answer:
60 delivery vans
Step-by-step explanation:
Smaller company:
Pickup truck : delivery van = 3 : 4
If the larger company has 45 pickup trucks
Let x = number of delivery vans
Larger company:
Pickup truck : delivery van = 45 : x
Equate both ratios
3 : 4 = 45 : x
3/4 = 45/x
Cross product
3 * x = 4 * 45
3x = 180
x = 180/3
x = 60
x = number of delivery vans = 60

Answer:
9/10 or 0.9
Step-by-step explanation:
When adding fractions, you look at each of them as an equal number, or a whole.
25+36
91
So, now all we have to do is convert it to it's closest form. (In tenths, since we are adding tenths.)
90
And it would be 9/10, or 0.9

Pythagoras lived over 2500 years ago. What is his theorem and why do we still use it today?
Answer:
The Pythagorean Theorem is helpful for two-dimensional navigation. You can use it along with two lengths to calculate the shortest path. The lengths north and west will be the triangle's two wings, and the diagonal will be the shortest line separating them. The same principles can be used for air navigation. He is best known in the modern day for the Pythagorean Theorem, a mathematical formula which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.

Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180
During a blind taste test of 8 different sodas, some people were asked to choose a favorite. Each dot represents one person. If the ratio of people choosing B to people choosing H stays the same, he many people will choose H if the number of people who choose B increases to 20
Answer:
20:5
Step-by-step explanation:
1. What is the ratio for B and H?
Ratio = 4 to 1 or 4:1
2. What is the question asking?
The question is increasing 5 to 20. What is the quotient of 20 and 5? 4! The question is basically multiplying B by 5. Now, since math is a very jealous subject, it needs to be done on the other side too! So you need to multiply the B, which is 1, by 5.
3. 1 x 5?
5
4. Answer
So, since B is 20 and H is 5, the ratio would be 20:5!

-6x+4(-2+8y)- 2y+ 4

3x+5⁰ 2x-25⁰ supplementary angles
Answer:
x=40, ∠ACB=125, ∠ACD= 55
Step-by-step explanation:
In order to solve this, you have to find the x-value. We know that these angles are supplementary, which means that the angles, ∠ACB and ∠ACD, both add up to 180°.
With this information, we can conclude 3x+5+2x-25=180.
To solve this equation for x,
1. Combine like terms
5x-20=180
2. Add 20 to both sides
5x=200
3. Divide both sides by 5.
x=40
Now we have the x-value. All we have left to do is plug that in to both of the equations for the angles.
1. ∠ACB: 3(40)+5
120+5
∠ACB = 125
2. ∠ACD: 2(40)-25
80-25
∠ACD = 55
Answer:x=40
Step-by-step explanation:
5x-20=180
5x=200
X=40
Explain how you can tell whether the sum of two integers is positive or negative, before adding them.
Answer:
The sum of any integer and its opposite is equal to zero. adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
Answer:
Step-by-step explanation:
The sum will have the same sign as the integer with the greater magnitude.
Example: the sum of -11 and 5 is -6, where the 6 takes the sign of -11 (which has a greater magnitude than does 5).
A running track consists of two parallel lines that are connected at each end but the curved boundary of a semicircle. The parallel lines are 30 meters long and 7 meters apart. Fine the area inside the running track.
Answer:
The area inside the running track is 248.5 m².
Step-by-step explanation:
The area inside the running track is given by the sum of the area of a rectangle and the area of a semicircle:
[tex] A_{t} = A_{r} + 2A_{c} [/tex]
[tex] A_{t} = x*(2r) + 2*(\frac{\pi r^{2}}{2}) [/tex]
Where:
x: is one side of the rectangle = 30 m
r: is the radius = half of the other side of the rectangle = 7/2 m = 3.5 m
Hence, the total area is:
[tex] A_{t} = 30*7 + \pi (3.5)^{2} = 248.5 m^{2} [/tex]
Therefore, the area inside the running track is 248.5 m².

One house key weighs 1/2
ounce.
Which model represents the total weight in ounces of 5 house keys?
Answer: 5/2
Step-by-step explanation:
If 1 house key weighs 1/2 ounce,
Then do 5×1/2 which is 5/2
or [tex]\frac{1key}{5key} \frac{1/2ounce}{?}[/tex]
With this cross multiply and get 1x=5/2
giving a total of 5/2 again when divided by 1.
