Answer:
-9x^2 - 15x.
-3x.
Step-by-step explanation:
The first quotient is -9x^2 - 15x.
To find the second result we divide the above by 3x + 5:
-3x
____________
3x + 5) -9x^2 - 15x
-9x^2 - 15x
-----------------
..................
The result is -3x.
Answer:
The answers are -9x²-15x and -3x
Step-by-step explanation:
First we need to find [tex]\frac{63x^3y + 105x^2y}{-7xy}[/tex].
[tex]\frac{63x^3y + 105x^2y}{-7xy}=\frac{63x^3y}{-7xy}+\frac{105x^2y}{-7xy}=-9x^2-15x[/tex]
Now we need to find value of z for which [tex]\frac{-9x^2-15x}{z}=3x+5[/tex]
[tex]\frac{-9x^2-15x}{z}=3x+5\\\\z=\frac{-9x^2-15x}{3x+5}=\frac{-3x(3x+5)}{3x+5}=-3x[/tex]
So the answers are -9x²-15x and -3x
