Answer:27t^5 units^3
Step-by-step explanation:
Answer:
we know that
The volume of a cube is equal to
where
s is the side length of the cube
we have
substitute in the formula
Remember the power rule
----> multiply the exponents
so
$475
7+6+7+5 = 25
25*19 = 475
$48
16 x 3 = 48
whats your question?
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
