Answer:
189
Step-by-step explanation:
The pyramid has four triangular faces and a square base.
The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.
The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.
The total surface area is:
A = 4(35) + 49
A = 189
Answer:
A and C
Step-by-step explanation:
I did the test and got a 100%
There are 4 quarts in a gallon and 2 pints in each quart
3 times 8 +3= 27 pints
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one
m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
