Question

Find two factors of 36, 54, and 180

Business and finance. Al purchased a new refrigerator that cost $736.12 with
interest included. He paid $100 as a down payment and agreed to pay the remainder
in 18 monthly payments. What amount will he be paying per month?


Evaluate each of the following expressions

[25 / (2 to the third power -3)] times 2

[(2+3)to second power-4 x5] +7




Insert grouping symbols in the proper place so that the given value of the expression is
obtained.

5-3x2+8x5-2; 28

l4l+l-3l

Answer 1

36= 2*2*3*3 54 = 3*3*3*2 180 = 3*3*2*2*5
So 9 and 18 are two common factors

(736.12-100)/18 = $35.34/month

[25/(2^3-3)]*2 = [25/5]*2 = 10
[(2+3)^2 -4*5]+7 =[5^2 -20]+7 = 25-20 +7 =12

(5-3)*2 + 8(5-2) = 28

l4l+l-3l = 7
