Determine the product of the following expressions 1. (x +3y)(9y² + x²-3xy)

2. (2a +3b)(5a²+ab+4b²)​

1. x^3+27y^3

2. 10a^3+17a^2b+11ab^2+12b^3

Step-by-step explanation:

$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
