If a = - 4 and b = 5x + 2i , then find the value of a ^ 3 b in fully simplified form.

  -320x -128i

Step-by-step explanation:

Put the values where the variables are and do the arithmetic.

  a³b = (-4)³(5x +2i) = -64(5x +2i) = -320x -128i

step-by-step :

$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
