Answer:
x=-16
Step-by-step explanation:
The given equation is:
x = 8a
which was written to find the value of x.
We have to find the value of x when the value of a is inserted as -2
So, putting the value
x = 8(-2)
x= -16
So the value of x when a = -2 is -16 ..
Answer:
8 inches
Step-by-step explanation:
Let w represent the width.
If the length is 14 inches longer than the width, it can be represented by w + 14.
Use the perimeter formula, p = 2l + 2w. Plug in 60 as the perimeter and w + 14 as l, then solve for w:
p = 2l + 2w
60 = 2(w + 14) + 2w
60 = 2w + 28 + 2w
60 = 4w + 28
32 = 4w
8 = w
So, the width is 8 inches
