Expand the following a. 2(x+3) b. 5(2x-4) c. 4(2x+1) d. 6(x-4y)!

Step-by-step explanation:

2x+6

10x-20

8x+4

6x-24y

So you multiply the number in front (left) of the bracket with the values inside the brackets so
a. it’s 2 multiply x plus 2 multiply 3 which gets you 2x + 6
b. 5 multiply 2x and 5 multiply -4 = 10x - 20
c. 4 multiply 2x and 4 multiply 1 = 8x + 4
d. 6 multiply x and 6 multiply -4y = 6x - 24y

Hi there.

If you want to find out the total, just multiply the rate per hour ($32.50) by the time (15 hours)

32.5 · 15 = $487.50
