Taking this step by step:
We can start by squaring 2x+5. Expanding (2x+5)(2x+5), we get:

Multiplying by 4pi, we then get:

This is equal to option C.

Answer:
<1=23
Step-by-step explanation:
If WXZ contains both <1 and <2, and <2 is 4 times <1, then we can set this up as x + 4x = 115
This is easily simplified to 5x = 115
Divide both sides by 5 and you will get x=23
Answer:
Step-by-step explanation:
1 - V = (l(w)h)/3 = (14·9.5·15)/3 = 665ft^3
2 - 73.5ft^3 C
3 - (8·8·12)/3=256in^3
4 - (1.5·2·4)/3 = 4cm^3
5 - (12·6·9)/3=216in^3
