Cylinder SA=2πrh+2πr<span>2
</span>Rectangular prism SA=2(wl+hl+hw)for the cylinder
SA= 904.78
for the rectangular prism
-you know that all the sides are 8 cm
h- 14
w-8
l-8
SA= 576
Add both together and you should get
1480.78
Answer: 9a-9b-6
7(3a−2b)+5b−3(4a+2)
Distribute:
7(3a−2b)+5b−3(4a+2)
=(7)(3a)+(7)(−2b)+5b+(−3)(4a)+(−3)(2)
=21a+−14b+5b+−12a+−6
Combine Like Terms:
=21a+−14b+5b+−12a+−6
=(21a+−12a)+(−14b+5b)+(−6)
=9a+−9b+−6
