Is/Was there a shape that goes with this?
Answer:
29 and 31 are the only primes.
Product is multiplication.
Let the number = x
3 *( X+7) = -36
Use distributive property:
3x +21 = -36
Subtract 21 from each side:
3x = -57
Divide both sides by 3:
x = -57 /3
x = -19
Check: 3 * (-19 +7) = 3 * -12 = -36
The number is -19
V=l*w*h
V= 15*8*3
V= 120*3
V= 360
