(w - 7)(w + 4)
w^2 - 7w + 4w - 28
w^2 - 3w - 28
Answer:
see below
Step-by-step explanation:
<em><u>sin(a+b) = sin(a)cos(b) + cos(a)sin(b)</u></em>
sin(π+q) = sin(π)cos(q) + cos(π)sin(q)
sin(π) = 0
cos(π) = -1
therefore
sin(π+q) = 0*cos(q) -sin(q) = -sin(q)
To solve for the true hourly wage simply add the 2 rates together.
20 dollars/500 hours = 2/50 = 0.04 dollars per hour.
The true rate would be $18.000 + $0.04 = $18.04 per hour.
Solution steps:
1. Add the two given fractions.
2. Subtract the sum from 10 to find your answer.
32+45 can be used to figure out the starting amount
