Answer:
Step-by-step explanation:
Given the perimeter of a rectangle P = 80 inches
Let 'x' be the width of a rectangle.
i.e.
x = width
As the length of a rectangle is three times its width. Thus,
length = 3x
We know that perimeter is the sum of all the sides (width and length) of a rectangle. So,
The Perimeter of a rectangle = 2(width + length)
substituting P = 80, width = x, length = 3x
80 = 2(x + 3x)
80 = 2x + 6x
80 = 8x
divide both sides by 8
80/8 = 8x/8
10 = x
Thus, the value of x = 10
Therefore,
The width = x = 10 inches
The length = 3x = 3(10) = 30 inches
Thus,

Answer:
a=1 is the answer
Step-by-step explanation:
let
p(x)=x³-2ax²+16
put x= -2
p(-2)=(-2)³-2a(-2)²+16
p(-2)=-8+16-8a
p(-2)=8-8a
as (x+2) is a factor of p(x) then p(x) is equal to zero
8-8a=0
8=8a
a=1
