Answer:
w = 23
l = 28
Step-by-step explanation:
w = width
l = w+5
P = 2 (l+w)
102 = 2( w+5+w)
102 = 2(2w+5)
Divide each side by 2
51 = 2w+5
Subtract 5
46 = 2w
Divide by 2
23 = w
The width is 23 and the length is 23+5 = 28
It's a 30-60-90 type of triangle
Palarell lines has equal slop. so the slope of a line parallel to y = -x + 7 is equal to the slope of y = -x + 7 = -1.
3x+x=96
(4x=96)/4
x=24
3(24)=72
Hector is 24 and his grandma is 72.
