Of the 10 possible molds, only two can have a base that is a square. That is, a base where the all 4 sides are equal. In this case, you can make the molds:
1,1,28 ; where the base is a 1x1 square with height 28 cm.
and
2,2,7 ; where the base is a 2x2 square with height 7 cm.

1: x + 8.23 = -5.14
Subtract 8.23 from both sides
x = -13.37
2: 4/9x = 32
Multiply both sides by 9 (basically, 4 is being divided by 9, so the opposite is to multiply).
(9 times 4, then divided by 9 is 4)
4x = 288
Divide both sides by 4 to isolate x
x = 72
Answer:
Step-by-step explanation:
basically the positive powers means the number multiplied by itself, that many times...3^3 would be 3x3x3 = 27
so: (2/3)^3 would be 2/3 x 2/3 x 2/3
