2x + (x + y)2
x= 3
y= 6
z= -2

87 is the (x+y)2 is supposed to be (x+y)^2

Step-by-step explanation:

2x+(x+y)2

2(3)+(3+6)2

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
