If we know that 180-5=128 that means that that equation must be equal to 128.
(2^3x+1)=128
By putting 128 into exponential form with a base of 2 you get 2^7:
(2^3x+1)=2^7
Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:
3x=6 to 3/3x = 6/2
This gives us a final answer of:
x=2
Answer:

Answer:
A) 30 cm
B) 20 cm
Explanation:
For the perimeter of rectangle B, I just imagined there was a cut horizontally through the middle. The length would be 5, since its half, and the width would be the same (10) because folding it into a rectangle only changes its length.
I added it up : 5+5+10+10= 30 cm
Rectangle B is 30 cm
For the perimeter of square C, you folded it again to make the width decrease by 5cm , so all the sides were 5cm.
5+5+5+5=20 cm
Square C is 20 cm
