Answer:
first option
Step-by-step explanation:
3x - 7y and - 7y + 3x are equivalent expressions
3x is positive and - 7y is negative
As long as the signs on their coefficients do not change then they can be reversed, that is
3x - 7y = - 7y + 3x
They’re all -4 ,, what exactly are you asking ?
Answer:
You are definitely correct! It is 81w^2.

What the. That ain’t a real question
Answer:

Explanation:
8c + 3 = −40c − 10
[ Step 1: Add 40c to both sides ]
8c + 3 + 40c = −40c − 10 + 40c
48c + 3 = −10
[ Step 2: Subtract 3 from both sides ]
48c + 3 − 3 = −10 − 3
48c = −13
[ Step 3: Divide both sides by 48 ]
48c / 48 = −13 / 48
C = -13 / 48 or -0.27083333333
