Answer:
x=-5
Step-by-step explanation:
Denominators are:
x+5, 5, and 5x+25
5 cannot be turned to 0 since it does not have a variable.
So we have x+5 and 5x+25.
eqyal each denominator to 0 since that is what we want.
x+5=0 5x+25=0
x=-5 5x=-25
x=-25/5
x=-5
∴x=-5 for all denominators to make 0.
Answer:
3/17
Step-by-step explanation:
-2x + 3(-5x + 1)
-2x -15x +3
-17x + 3
17x = 3
x = 3/17
Answer:
30x^5 + 15x^4 + 105x^3
Step-by-step explanation:
V = l*w*h
l = 3x
w = 5x^2
h = 2x^2 + x + 7
l*w = 3x * 5x^2 = 15x^3 (add exponents when multiplying variables)
l*w = 15x^3
V = l*w*h = 15x^3(2x^2 + x + 7) = 30x^5 + 15x^4 + 105x^3
