Answer:
x=-35
Step-by-step explanation:
136+12x=-4(1-2x)
136+12x=-4+8x
+4 +4
140+12x-12x=8x-12x
140/-4=-4x/-4
x= -35
Answer:
Option c - 67.5
Step-by-step explanation:
Base= 15
Height = 9
Area= 1/2 x b h = 1/2 x 9 x 15 = 67.5 feet
This would be 14137.17.
V=4/3 x π x r^3 = 4/3 x π x 15^3 ≈ 14137.16694
A linear equation, as the exponent of x is one
