a² + 10a + 16
Find two numbers whose product equals 16 and sum equals 10:
<u>Product = 16</u> <u>Sum = 10</u>
1 * 16 1 + 16 = 17 <em>doesn't work</em>
2 * 8 2 + 8 = 10 THIS WORKS!
4 * 4 4 + 4 = 8 <em>doesn't work</em>
Since 2 & 8 satisfy our requirements, those are the values that go into the parentheses.
Answer: (a + 2)(a + 8)
Note: when there is a coefficient for a², a different method is used to find the factors.

Answer:
100 hours
Step-by-step explanation:
If Johnny is paid 245.00 as a one time fee for all his jobs then the total money he is paid is 2245.00
We need to separate the hourly fee from the one-time fee so we subtract 245 from 2245. This leaves us with 2000 dollars.
We know that he will be paid 20 dollars per hour so we need to divide 2000 by 20. This leaves us with 100.
<h2>Therefore Johnny worked 100 hours</h2>
