Answer:
Step-by-step explanation:
Given that: The perimeter of a square is: 32x - 12.8
As we all know that, the formula to find the perimeter of a square is:
Sum of the 4 side = 4* length of the side
=> the length of 1 side: The perimeter of a square / 4
In this situation, we have length of 1 side side is:
(32x - 12.8) / 4
= 32/4x - 12.8/4
= 8x - 3.2
The 1st equivalent expressions for the perimeter: 4 *(8x - 3.2)
The 2nd equivalent expressions for the perimeter: (8x - 3.2) + (8x - 3.2) + (8x - 3.2) + (8x - 3.2)
The 3rd equivalent expressions for the perimeter: 2*(8x - 3.2) + 2*(8x - 3.2)

Step-by-step explanation:
Let
l------> the length side of the rectangle
w----> the width side of a rectangle
b----> the base of the triangle
h----> the height of the triangle
we know that
the area of the yard is equal to
Solve for b------> ( that means clear variable b)
Subtract 
both sides
Divide by 
both sides
therefore
<u>the answer is the option B</u>
The quantity A minus l times w all divided by 0.5 times h
Answer:
Step-by-step explanation:
Let 
represent the cost of the torch and 
represent the cost of the battery.
The torch and a battery cost £2.50 altogether.
The torch costs £2.00 more than the battery.
We substitute the second equation into the first equation to get;
£2.50
The price of the battery is £0.25
We express this as a fraction of the total cost which is £2.50 to get;
