Answer:
The volume of the smaller solid is 72 cm.
Step-by-step explanation:
Given that two similar solids have surface areas of 48cm and 108cm respectively, to find the volume of the smaller solid if the bigger one has a volume of 162cm the following calculation must be performed:
108 = 162
48 = X
48 x 162/108 = X
7776/108 = X
72 = X
Therefore, the volume of the smaller solid is 72 cm.
Answer:
<h3>x = -2 and 7</h3>
Step-by-step explanation:
- x^2 - 5x - 14 = 0
- x^2 - ( 7 - 2 )x - 14 = 0
- x^2 - 7x + 2x - 14 = 0
- x ( x - 7 ) + 2(x - 7) = 0
- (x + 2) (x - 7) = 0
- x = -2 and 7
