What’s the answer ??? Help
Answer:
It's B. (2x+5) (x+4)
Answer:
b
Step-by-step explanation:
2x²+13x+20
You can just try all the answers if you'd like and see which one equals 2x²+13x+20.
Using FOIL for all of them:
a. (2x-5)(x-4) = 2x²-8x-5x+20 = 2x²-13x+20
b. (2x+5)(x+4) = 2x²+8x+5x+20 = 2x²+13x+20
c. (2x+2)(x+10) = 2x²+20x+2x+20 = 2x²+22x+20
d. is obviously not correct since we already have an answer.
Our answer is b. (2x+5)(x+4)

Viktoriya solved an equation as shown below.
5 (x - 2) -3 x = 2 (x - 3) - 16
5 x - 10 -3 x = 2 x -6 = 16
2 x - 10 = 2 x - 22.
-10 = -22.
She says that the equation has infinitely many solutions. Which describes Viktoriya’s error?
A.) Viktoriya used the distributive property incorrectly when she found the solution.
B.) Viktoriya should have said that the equation has no solution.
C.) Viktoriya should have continued to solve the equation to find that x = 0.
D.) Viktoriya should have said that the equation has one unique solution.
Answer:
B
Step-by-step explanation:
When you finish solving an equation and find the answer to be that two numbers are equal to each other when they are in fact, this means that the equation has no solutions because not values could make it true. Hpope this helps!

2x + 5y = 3
-2x - y = 5
Answer:
x = -7/2, y=2
Step-by-step explanation:
2x + 5y = 3
-2x - y = 5
Add the two equations together to eliminate x
2x + 5y = 3
-2x - y = 5
------------------------
4y = 8
Divide each side by 4
4y/4 = 8/4
y =2
Now find x
2x +5y =3
2x +5(2) =3
2x+10 =3
Subtract 10
2x = -7
Divide by 2
2x/2 = -7/2
x = -7/2
What is (2x+3)(x- 8)= 3+2(x- 5)(x + 5)
Answer:
- 23/13
Step-by-step explanation:
first, we do the FOIL multiplication (First, Outer, Inner, Last)
(2x+3)(x- 8)= 3+2(x- 5)(x + 5)
2x(x-8) + 3(x-8) = 3 + 2(x(x+5) - 5(x+5))
2x² - 16x + 3x - 24 = 3 + 2(x² + 5x - 5x -25)
2x² - 16x + 3x - 24 = 3 + 2(x² - 25)
2x² - 16x + 3x - 24 = 3 + 2x² - 50
2x² - 13x - 24 = 3 + 2x² - 50
after that move all component which have x to the left
2x² - 2x² - 13x = 3 - 50 + 24
-13x = 23
x = - 23/13
Answer:
x^3= 11/-7
Step-by-step explanation:
(2x+3)(x- 8)= 3+2(x- 5)(x + 5)=
2x^2-16x+3x-24= 3+2x-10+x+5
-11x-24= -2+3x
-11x^2 -24 = -2+3x
-11x^2-3x = -2+24
-14x^3 = 22
x^3 = 22/ -14
x^3 = 11/-7

Step-by-step explanation:
Charlotte has been working for her company for x years. Travis has been working for the same company exactly 3 years longer than Charlotte. What is the range of the relationship?
Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
Charlotte has been working for her company for x years.
Travis has been working for the same company exactly 3 years longer than Charlotte.
This means that Travis have 3 years extra than Charlotte.
So, the range of the relationship is
y>3.

What is the value of x?
Answer:
x = 20
Step-by-step explanation:
The angles are vertical angles and we know that vertical angles are equal
x+40 = 3x
Subtract x from each side
x+40-x = 3x-x
40 = 2x
Divide each side by 2
40/2 = 2x/2
20 =x
Answer:
The value of [tex]x[/tex]:
[tex]x = 20[/tex]
Step-by-step explanation:
-Since, one angle with the measure [tex]x + 40[/tex] and another angle with measure [tex]3x[/tex] are vertical angles, they equal each other. So, it will be written as:
[tex]x + 40 = 3x[/tex]
-After you have formed an equation, you switch the equation and you solve for the value of [tex]x[/tex]:
[tex]x + 40 = 3x[/tex]
[tex]x - x + 40 = 3x -x[/tex]
[tex]40 = 2x[/tex]
[tex]\frac{40}{2} = \frac{2x}{2}[/tex]
[tex]20 = x[/tex]
So, the final answer is [tex]20 = x[/tex] or [tex]x = 20[/tex] (They are both the same, you just switch them).

The floor of the cage measures 11 yardyard wide by 66 feetfeet long. One bag of shavings covers 55 square feetfeet. How many bags will HarperHarper have to buy to cover the floor of the cage? Explain.
Answer:
3 3/5 bags
Step-by-step explanation:
We have to find the surface area of the floor of the cage first.
The cage measures 1 yard wide by 6 feet long.
1 yard = 3 feet
The floor of the cage is rectangular, so, the surface area of the floor of the cage is therefore:
3 * 6 = 18 square feet
One bag of shavings covers 5 square feet.
To find the number of bags we need to cover the floor, we divide the surface area of the floor by the number of bags per square feet.
The number of bags needed for the floor of the cage is therefore :
18 / 5 = 3 3/5 bags

Jeffrey estimates there's a 40% chance to eat pizza for dinner, it's 60% chance he'll drink cold out, and it's 30% chance to eat pizza and drink Cola. What's the probability of Jeffrey drinking cola, if he eats Pizza?
Answer:
a. 75%
Step-by-step explanation:
Let "p" represent the probability that Jeffrey will eat pizza, and "c" represent the probability that he will drink cola.
We are given ...
P(p) = 0.40
P(p&c) = 0.30
The conditional probability of interest is ...
P(c|p) = P(p&c)/P(p) = 0.30/0.40 = 0.75
The probability Jeffrey will drink cola, given that he eats pizza, is about 0.75.

Answer:
if we assume that
tan = opp/adj
then we can find the hypotenus by using phytagoras law
h² = o² + a²
h² = (m-1)² + (2√m)²
h² = m² - 2m + 1 + 4m
h² = m² + 2m + 1
then we factorized become
h² = (m + 1)²
h = m+1
so for sin x = opp/hyp = (m-1)/(m+1)

Two numbers add to 200. The first is 20 less than the second. What are the numbers?
Answer:
Step-by-step explanation:
Let's call the first number x.
We can write an equation representing the problem using x:
x+x+20=200 (because the second number is 20 more than the first, or x)
Combine like terms: 2x+20=200
Subtract 20 from each side of the equation: 2x=180
Divide by 2: x=90
The first number is 90, the second number is 110.
