1) Let 'A' = Alex's Height
A=x^2
2) Let 'D' = Doug's Height
A+5=D
3) D=x^2 + 5
4) A= 24^2 = 576 (inches)
-Alex is 576 inches tall.
D= 576+5
D=581 Inches
-Doug is 581 inches tall.
5) X show's Alex's brother's height. After the height is squared it equals Alex's height.
Answer:
y=-1/2x+3/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-1)
m=-2/4
m=-1/2
y-y1=m(x-x1)
y-1=-1/2(x-1)
y=-1/2x+1/2+1
y=-1/2x+1/2+2/2
y=-1/2x+3/2
Area of a trapezoid = a+b+c x h
10 + 5 +12 = 27 x h
27h = 27 x 1.5 = 40.5
