Answer:
Step-by-step explanation:
11.-3(2x-8)=-12
-6x+24=-12
-6x=-12-24
x=-36/-6
x=6
12.4(6+2x)=0
24+8x=0
8x=0-24
x=-24/8
x=-3
13.3x+2x+6=-15
5x+6=-15
5x=-15-6
x=-21/5
14.4=-2(x+3)
4=-2x-6
4+6=-2x
10/-2=x
-5=x
15.27=46+2x-x
27=46+x
27-46=x
-19=x

|______<base=60 feet(b)
c^2=a^2+b^2
c^2=40^2+60^2
c^2=5200 feet^2
c=(5200)^(1/2)
c=72.11102551 feet
