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:
The answer is (8a)+(a7)
Step-by-step explanation:
From 8(a+7) it can also be written as (8a)+(a7)
Answer:
39
Step-by-step explanation:
The chords are equal to eachother. First multiply their divided lengths together:
9(3x-9)=21(x+1)
27x-81=21x+21
x=17
CD= 21+x+1
21+17+1=39
CD= 39

Answer:
Given: P.E=6.0J Height (h)= 3m g=9.8m/s^2
mass=?
Formula: P.E=mgh
m=P.E/gh
Application:<em> </em><em>To</em><em> </em><em>find</em><em> </em><em>mass</em><em> </em><em>of</em><em> </em><em>an</em><em> </em><em>apple</em>
Answer+unit= 0.2 kg
Step-by-step explanation:
m=P.E/gh
= 6kgm^2/s^2 ÷ 9.8m/s^2*3m
=0.2kg
