Answer:
A = 18 cm²
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = area of base (A) × height
Here V = 216 cm³ and h = 12 cm , then
A × 12 = 216 ( divide both sides by 12 )
A = 18 cm² ← area of base
Answer:
Step-by-step explanation:
Recall that the quadratic formula gives you the pattern to follow in order to find the solutions to a quadratic equation of the form: 
It tells us that we need to use the parameters 
and 
in the following formula in order to get the answers for the x-values that solve it:
so, in our case, 
, 
, and 
then, replacing these values in the formula, we obtain:
Which looks like the third expression you are listing (although it is a little hard to read)
Answer:
0
