Last Question
Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.
A

=(6*-2) / (5*3) = - 12/15 = -4/5
B
= (7*5) / (4*3) = 35 / 12 = 2 11/12
C
Impossible to do 4/0 cannot be done.
D

= (-2*-4)/(3*5) =
8/15
Answer:
(b) –4g^4 – 3g^3 + 4g^2 + 5g + 3
Step-by-step explanation:
The simplification process is described and partially carried out. We are to finish by combining like terms and writing the result in standard form.
__
<h3>Combine Like Terms</h3>
g^2 + (–4g^4) + 5g + 9 + (–3g^3) + 3g^2 + (–6) . . . . given
The like terms are the g^2 terms and the constants.
= (1 +3)g^2 + (–4g^4) +5g +(9 +(–6)) +(–3g^3)
= 4g^2 +(–4g^4) +5g +3 +(–3g^3)
__
<h3>Write in Standard Form</h3>
In this form, the terms are written in order of decreasing degree.
= –4g^4 –3g^3 +4g^2 +5g +3
