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
0 and 1 cause both f(x) and g(x) values at that point are the same
A) 3 centerpieces per hour because 15/5 = 3
b) 14 hours, because 3 goes into 42 14 times exactly.
Hope this helps!
Answer: 20
Step-by-step explanation:
f(-4) = -4² - (-4)
f(-4) = 16 + 4
f(-4) = 20
8x - 32 = 6 - 9x
17x = 38
x = 38/17
