I must assume that you meant the following:
10(Q-3R)
P = ----------------
R
Multiplying both sides by R, we get PR = 10R(Q-3R), or PR = 10RQ - 30R^2.
Rearranging these terms so that powers of R are in descending order:
30R^2 - 10RQ + PR = 0
Factoring out R, we get
R(30R - 10Q + P) = 0. This has two solutions:
R = 0, and 10Q - P
30R = 10Q - P, so that R = --------------

<em>C) 52 m²</em>
- Step-by-step explanation:
<em>A = 2(lw + lh + wh)</em>
<em>l = 4m</em>
<em>w = 3m</em>
<em>h = 2m</em>
<em>A = 2(4m×3m + 4m×2m + 3m×2m)</em>
<em>= 2(12m² + 8m² + 6m²)</em>
<em>= 2×26m²</em>
<em>= 52m²</em>
Answer:D
Step-by-step explanation:
I'm prolly wrong so sorry
Answer:
A
Step-by-step explanation:
B - 11,015 = 2t ( add 11,015 to both sides )
B = 2t + 11,015 , that is
B(t) = 2t + 11,015
Answer:
-4
Step-by-step explanation:
cause 4x4 = 16 and 4+5 =o so you could use four in each one right
