8) factor 6+17g+10g^2
10g^2+17g+6
(5g+6)(2g+1)
C is the answer.
9) which one is a perfect square?
4x^2-14x+49 doesn't factor
4x^2-28x+49=(2x-7)(2x-7)
x^2-x+1 doesn't factor
x^2-2x+2 doesn't factor
B is the answer.
11) factor y^2-2y-48
(y+6)(y-8)
D is the answer
12) for the last one you can multiply the answers out of factor.
Sorry this took forever. It's hard to use the website cuz I'm used to the app.

Answer:
None
If you already made 90K through October then based on this information (or lack of additional tax information for the remainder of the income) you would owe nothing.
To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))
Answer:
Step-by-step explanation:
The equation for this free fall problem is
where h(t) is the height of the pebble from the ground at any time t. If we are looking for the time it takes the pebble to hit the ground, knowing that at ground level the height is 0, we set the quadratic equal to 0 and solve for t:
and
and
so
t = -8, 8
Since time will never be negative,
t = 8 seconds
