5.25 -0.75 a is the expression, but to answer the question on the paper you would plug in the number of belts being made into where the variable a is. Hope this helps!
Answer: x=11
Step-by-step explanation:
First, since angle A and angle B are vertical angles, that means that they are congruent. If they are congruent, then the m of angle A equals the measure of angle B. So, (3x+3)=(4x-8). Simplify using algebra so that in the end, you will find that x=11.
3x+3=4x-8
3=x-8
11=x
The answer is 112 in^2
area of the square :
area of the triangle :
area of the whole shape :
good luck
The answer for the green box is - 2p=18
First add like terms
53 = -14 + 7z
now add 14 to both sides
67 = 7z
divide both sides by 7
9.5714285 = z
