-1 = 3x - 7
Add +7 to each side
6 = 3x
Divide each side by 3
X = 2
f(-1) = 3 * 2 - 7
To work out the surface area of a triangular prism:
Base: l x w
= 4 x 7
= 28 feet
Top: l x w
= 5 x 7
= 35 feet
Two sides: 1/2 x b x h
= 1/2 x 4 x 3
= 6 + 6 (for the other side)
= 12 feet
Left side: l x w
= 3 x 7
= 21
Add all of them up:
= 28 + 35 + 12 + 21
= 96 square feet
Hello!
There are 4 cheetahs. There are 3 times as many elephants than cheetahs. Multiply:
4 • 3 = 12
12 + 4 = 16
