Answer:
<u>Simply</u>
1 - x = 16 - 4x when the x is 5:
Substitute x for 5, by replacing x with 5.
1 - (5) = 16 - 4(5)
1 - 5 = 16 - (4 * 5)
1 - 5 = 16 - 20
-4 = -4
<u>LHS - RHS</u>
It is better to show this by doing each side individually - Left Hand Side (LHS) and Right Hand Side (RHS).
LHS
1 - x when x = 5
1 - 5 = -4
RHS
16 - 4x when x = 5
16 - 4(5) = 16 - 20 = -4
Answer:
<em>V/3r² </em>
Step-by-step explanation:
We are to make h the subject of the formula as shown;
V = 3r²h
Divide both sides by 3r²
V/3r² = 3r²h/3r²
V/3r² = h
Rearrange
h = V/3r²
<em>Hence the formula to calculate the height h is V/3r² </em>
