Y=mx+b
4y=5x-12
y=5/4x-3
so you change your y intercept (-3) to your other y intercept (15)
y=5/4x+15
3+9+0+5+2= 19
19 is not divisible by 3 so the answer is no
Perimeter of Figure = Perimeter of 2 semicircles + Measures of two straight line
P = 2(πr) + 2*x
P = 2*3.14*7 + 2*13
P = 43.96 + 26
P = 69.96 m
In short, Your Answer would be: Option C
Hope this helps!
