The perimeter is needed for fencing, because you only fence the edges of property.
Answer:
20
Step-by-step explanation:
8x=6x+5 (subtract 6x from both sides)
2x =5 (divide by 2 both sides)
x=2.5
8x= 8*2.5 = 20 (substitute 2.5 for x)
or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)
Answer:
volume is cubed
area is squared
Step-by-step explanation:
Answer:
x=-12
Step-by-step explanation:
x2-36=5x
add 36 to both sides
x2=5x+36
subtract 5x from both sides
x(-3)=36
divide both sides by -3
x=-12
substitute to prove right
(-12)2-36=5(-12)
-24-36=-60
-60=-60
