Answer: x = 0 and x = 7
Step-by-step explanation:
9x^2 - 63x = 0.
We can factor out 9x from both terms on the left side:
9x(x - 7) = 0.
To be equal to 0, one of the terms has to be 0.
Therefore, either 9x = 0 or x - 7 = 0.
First, we solve the case where 9x = 0.
Then, x = 0.
Second, we solve the case where x - 7 = 0.
We add 7 to both sides:
So, x = 7
X+4multiply by y=7
Moved these terms to left-7
It becomes X+4 multiple y-7=0
X+4 multiple y-7=0

Answer:-2n^2-2n+19
Step-by-step explanation:
To find the sum of 8n-n^2+12 and 7-n^2-10n
We collect like terms
-n^2-n^2+8n-10n+12+7
-2n^2-2n+19
