I will mark you as brainlis if you andwer this all.
dimaraw [331]

Answer: See below

Step-by-step explanation:

27.  -(a-3)

28.  (b-1)(b+3)

29.  (c+4)(c+5)

30.  d(d+5)

31.  -(3/4)(2e-5)

Sorry - I don't have time to enter the details.  Look for areas where the expressions can be factored in a manner that forms as many equivalent expressions in both the numerator and denominator.

For example:  In problem 30:

(5d-20)/(d^2+d-20) * [??]/20d = 1/4

Factor:  

  <u>(5(d-4))</u>       <u>d(d+5)</u>        = 1/4

(d-4)(d+5<u>)</u>       20d

The (d-4), d+5, and d terms cancel, leaving

5/20 = 1/4

azamat
You must distribute first.
8 times (3x-2)= 24x-16
2 times (12x-5.5)= 24x-11
What you have left is
(24x-16)-(24x-11)
24x-24x=0
-16- -11=-5
The answer is -5
