Answer:
(x-10)(x+10)
Step-by-step explanation:
x^2 – 100
This is the difference of squares
x^2 - 10^2
We know that (a^2 - b^2) = (a-b) (a+b)
(x-10)(x+10)
P = 2(L + W)
P = 200
L = W + 80
200 = 2(W + 80 + W)
200 = 2(2W + 80)
200 = 4W + 160
200 - 160 = 4W
40 = 4W
40/4 = W
10 = W.........the width is 10 yds
6.83 as a mixed number is:
6 83/100
Kim is X
Jordan= x+7
So J x 4=200
This means 4(x+7) = 200
x=43
43+7=50
50 x 4=200
so Kim is 43 and Jordan is 50.
