Answer:

x= - 1   ; z = - 9

Step-by-step explanation:

The requester asked for 8 and 11, but I can't see the problem in the picture.

Here are 7 and 10:

#7 5x - 4x + 2 = 1

Combine 5x and -4x to get x

x + 2 = 1

Subtract 2 from both sides

x = -1

#10 -40/2 = z - 11

Simplify -40/2 to get -20

-20 = z - 11

Add 11 to both sides

z = -9

If you want 8 and 11, reupload the problem with a picture that includes them.

Find the surface area of the composite solid. Leave your answer in terms of pi.
bonufazy [111]
Total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:
cone: πrL = π(5cm)(13cm) = 65πcm²
cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²
base: πr² = π(5cm)² = 25πcm²
total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²
