It would be 725/1000 because u are 3 spaces after the decimal
Did you mean -21(-2-5)+(-14)+6(8-4.3) ?
If that, the answer is 155.2:)) im sorry if im wrong:((
If 1 of ur factors is 9...and the sum of ur factors is 13....then ur other factor is (13 - 9) = 4
so u have 2 factors, 9 and 4, and u r the product, then u r (9 * 4) = 36 <==
Are they asking for the surface area?
