Step-by-step explanation:
4- -5/9-9
9/0

If I did this right it should be 8.
New pump = (Old Pump * Total) / (Old Pump - Total)
New pump = (14 * 6) / (14 -6)
New pump = (84) / (8)
New Pump = 10.5 hours
Answer:
x = +2, x = -2
Step-by-step explanation:
The equation to solve in this problem is

The first step we do is to subtract 35 on both sides of the equation, so we get:

Now we simplify the equation by dividing both terms by 10:

Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:

Where here,
a = x
b = 2
So we can rewrite the equation as:

And this equation is zero when either one of the two factors is zero, so the two solutions are:

Angle A = angle U since they're both right angles (both 90 degrees). This is what the square marker means.
segment AC = segment UW
Angle C = angle W because they have the same angle marker
---------------------
we have two pairs of congruent angles, with segments between them that are congruent. So we use the ASA property
The final answer is choice E.
