Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
Cubed means you have to multiply it by the other number like an exponent so that means the answer is z3
Answer:
30
120
706.5
Step-by-step explanation:
circumference= 94.2 inches, circumference is pi x diameter so-
diameter = 94.2/pi inches.
Using 3.14 as an approximation for pi we get:
Diameter=30 inches.
So would need a length of at least
4x30 = 120 inches of felt for four wheels.
The area of the circular wheel is pi x diameter 2/4 square inches.
Area is 706.5 square inches which is how much felt is needed to cover one wheel.
