Find the sum of (4u with exponent of 2 -7u +6 and 10u with the exponent of 2 -7u -9

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

there are infinitely many solutions.

1) letter c.

2) 4 square root of 9

hope this
