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
15, since 16-1=15, and you can use the y-intercepts as points to measure the distance from.

Answer:
Degree is 6
Step-by-step explanation:
Solving given polynomial gives -3x^3y^3-2.5xz^2
as this polynomial involves two variables so we'll add the powers on variables in each term
first term: -3x^3y^3, add powers on x and y variables which turns out to be 6
Second term: 2.5xz^2, adding powers on x and z variable results in 3
As degree is the highest power among different powers on terms so here the degree is 6
