Answer:
O 3x+12
Step-by-step explanation:
3(x + 4) = (3 · x) + (3 · 4)
= 3x + 12
Answer:
-4 (2p+ 3) = -(p+1) - 2
-8p -12 = -p-1-2
-7p=9
p=-9/7

Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
