The perimeter of a square is a^2. In this case a= (4x-2y) so a^2=(4x-2y)^2 , a^2={16(x)^2-16xy+4(y)^2}
Answer:
what form?
Step-by-step explanation:
I think it is the first one could be wrong tho
Answer: length = 13
Width = 22
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length × width)
The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that
2[(3x - 8) + (x + 3)] = 70
Dividing both sides of the equation by 2, it becomes
3x - 8 + x + 3 = 35
3x + x - 8 + 3 = 35
4x - 5 = 35
4x = 35 + 5 = 40
x = 40/4
x = 10
Length = x + 3 = 10 + 3
Length = 13
Width = 3x - 8 = 3 × 10 - 8
Width = 22
32.5...
125x26 = 3250 divided by 100 = 32.5
hope this helps!
