Step-by-step explanation:
A (the first one)
.............
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.

Answer:
35
Step-by-step explanation:
.54 can be rounded up to 1
So, 34.54 would become 35
4n - 6m = -2
Let n = -2
4(-2) - 6m = -2
-8 - 6m = -2
-6m = -2 +8
-6m = 6
m = 6/-6
m = -1
So, when n is -2, m is -1.
Now, do the same when n is -1 and again when n is 0.
