Answer:
The answer is B I just took the test:)
Step-by-step explanation:
A = 3x
b = 2x+25
180 = a + b
180 = 3x + 2x + 25
180 = 5x + 25
155 = 5x
x = 31
a = 3*31 = 93
b = 2*31 + 25 = 87
Answer:

Step-by-step explanation:

Since the area of the rectangle is 30, we know the following:
(5)(x-2) = 30
Divide both sides by 5
x-2 = 6
Add both sides by 2
x = 8
That's your answer.
Have an awesome day! :)
Answer: The answer is x = +/-
.
Step-by-step explanation: You can solve this by simply rearranging the equation to make x by itself.
-
= -y - 1
Then cancel out the -1 by dividing it through to obtain.

The final step is to square root both sides to get rid of the exponent.
x = 
This should be the answer since square roots have a +/-.
