Answer:
753.6 ft^2
Step-by-step explanation:
given:
radius=9 ft
height=13 ft
total surface area of cylinder=2πrh+2πr2
=2*3.14*9*13 + 2*3.14*(9)^2
=244.92 + 2*3.14*81
=244.92 + 508.68
=753.6 ft^2
180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25
Answer:
With distribution
-2(3) + -2(-4) + -2(-8) + -2(7)
= -6 + 8 + 16 - 14
= 4
Without distribution
-2 (3 -4 -8 + 7)
= -2 (-2)
= 4
