Answer:
(x-2) (x+6)
Step-by-step explanation:
If it is written like this:
[tex]x^{2} +4x + 3 = 15[/tex]
To focus on the equation on the left rewrite the equation equal to the value of zero.
(x-2) (x +6) = 0
The answer is (x-2) (x+6)

find the value of x so that the function has the given value. n(x)= -1/4x+11; n(x)=10
Answer:
x = 4
Step-by-step explanation:
10 = -1/4 x + 11
10 - 11 = -1/4 x
-1 = - 1/4 x
x = 4
WILL PICK BRAINLIEST! A line l has slope 2. What is the slope of line l1 if l1 ⊥ l ? What is the slope of l2 if l2 ∥ l ?
Answer:
1. The slope of line l1 is -1/2
2. The slope of l2 is 2
Step-by-step explanation:
Perpendicular lines have opposite inverse slopes. The inverse of 2 is 1/2 and the opposite is -2. Therefore the opposite inverse slope of the perpendicular line, l1, is -1/2
When two lines are parallel, the slopes are the same. l2 is parallel to l therefore, they share the same slope.

A right triangle is graphed on a coordinate plane. Find the length of the hypotenuse. Round your answer to the nearest tenth.
Answer:
7.6
Step-by-step explanation:
From the graph, we know the lengths of two legs.
a = 3
b = 7
Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember, a^2 + b^2 = c^2)
c = √a2 + √b2
= √(7)2 + √(3)2
= √49 + √9
= √58
= 7.6
Answer:7.6
Step-by-step explanation:
What is the range of the function f(x) = -2x + 5 when the domain is {-5, 5}.
Answer:
{-5,15}
Step-by-step explanation:
because this function is constantly decreasing, we can get our range by looking at the endpoints:
f(-5) = 15
f(5) = -5
i need help finding the value of x and the measure of each angle
Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Answer:
x = 7
m∠B = 65
m∠A = 45
Step-by-step explanation:
So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.
180 - 70 = 110
Now we can set both equations equal to 110.
2 + 9x + 7x - 4 = 110
Now simplify.
2 + 9x + 7x - 4 = 110
2 + 16x - 4 = 110
16x - 2 = 110
+2 +2
------------------
16x = 112
÷16 ÷16
-----------------
x = 7
So now you can just plug 7 in for x to check your answers
2 + 9(7) = 65
7(7) - 4 = 45
65 + 45 + 70 = 180
In the scale used on a blueprint, 1/5 inches represents 3 feet. On the blueprint, what is the length of a room with an actual length of 30 feet?
(You have to convert the fraction to a decimal first)
A. 6 in
B. 2 in
C. 1/2 in
D. 2 1/2 in
9514 1404 393
Answer:
B. 2 in
Step-by-step explanation:
The lengths are proportional, so you have ...
blueprint length / room length = (1/5 in)/(3 ft) = (x in)/(30 ft)
Multiplying by 30 ft gives ...
x in = (1/5 in)(30/3) = 10/5 in = 2 in . . . . . note that units of ft cancel
The blueprint length of the room is 2 inches.

Comment on "convert the fraction"
As a general rule, you can work math problems with the numbers in any convenient form: fractions, decimals, scientific notation, percentages. Your calculator or your mental arithmetic methods may prefer one form over another, but conversion isn't always necessary.

Juan noticed that if he takes the opposite of his age and
adds 40, he gets the number 28: How old is Juan? Write
an equation and solve. Use a for his age.
Answer:
-a + 40 = 28, a = 12
Step-by-step explanation:
If he takes the opposite of his age, that means the current number is negative. We can get -a + 40 = 28, we can then simplify by subtracting both sides by 40 and getting -a = -12 which is equal to a = 12

5+7n>-37 and n +8 <4
Solve each compound iniquity and graph its solution.
Answer:
-6 < n < -4
Step-by-step explanation:
Solving the inequality 5 + 7n > -37 :
5 + 7n > -37
⇔ 7n > -37 - 5
⇔ 7n > -42
⇔ n > -42/7
⇔ n > -6
Solving the inequality n + 8 < 4 :
n + 8 < 4
⇔ n < 4 - 8
⇔ n < -4
Then , the solution to the compound inequality
5 + 7n > -37 and n + 8 < 4 is :
All real numbers n ,where -6 < n < -4
The solution in interval notation (-6 , -4)
In a triangle, one side length is 4 feet and another side length is 7 feet. Which answers are possible lengths for the third side?
Answer:
3
Step-by-step explanation:
You might just think that I subtracted but on the triangle the last side is the base which is always smaller.
Answer: The answers are 4, 8, 10
To solve, you must use the Triangle Inequality Rule -
Subtract 7-4=3; therefore, the 3rd side must be greater than 3
Add 7+4=11; therefore, the 3rd side must also be less than 11
Any number greater than 3 or less than 11 would be correct.

(screenshot included) I need to find TWO ways to get the area of the ABC triangle, I did the (base x height)÷2, so (9.6x3.6)÷2 and got 17.28, but I can't find any other way to solve this. PLEASE HELP
Answer: 17.28 cm^2
Step-by-step explanation:
You can also use AC as the base, then BE will be the height to that.
Assuming you want your answer in cm^2, then (7.2*4.8)/2 = 17.28 cm^2.
Answer:
2160mm
Step-by-step explanation:
Recall that to find the area of a triangle, you need to follow the formula:
A = 1/2 * b * h
But first we need to convert the cm to mm, or else our calculations will be incorrect:
9.6 cm = 96 mm
4.8 cm = 48 mm
Let's cut the triangle into two pieces to make it easier for us to find the area. We'll start with triangle ACD:
A = 1/2 * 36 * 72
A = 1/2 * 2592
A = 1296 mm
Now that we have the area for triangle ACD, let's move on to try to find the area of triangle DCB:
A = 1/2 * 36 * 48
A = 1/2 * 1728
A = 864
It's time to add them up:
(DCB) 864 + (ACD) 1296 = 2160
The area of the triangle is 2160 mm.
