Answer:
c + d - d = c
Step-by-step explanation:
c = c
d - d = 0
c + 0 = c
c = c
7. D
lateral surface area=
2 × pi × 3.0625 × 6.625 = 127.48
8. A 14.5in^2
A=l×w
5 × 0.5 = 2.5
A=(bh)/2
(6 × 4)/2
24/2= 12
2.5 + 12= 14.5in^2
9. D. l=15 w=12
Ratio:
l/w =l/w
15/30 = x/24
15 × 24 = 360
360/30 = 12
15/30 = 12/24
The other answers don't match if you plug them into the equation. For example, C, if you plug in 24 over 30, solving for x over 24, you'd get 19.2 for x instead of 18.
I hope this helped. Sorry if my explanation didn't make sense.
Answer:
1, 2, 3, 6, 9, 18. Factors of 21: 1, 3, 7. The highest number that both sets contain is 3, so the GCF will be 3.
