112 is 80% of 140.
80% can be written as 0.80 or 0.8.
how i got 140 is by finding the x value of this equation: 0.8x=112
to find the x, i divided 0.8 from both sides,
0.8 divided by 0.8 cancel out.
112 divided by 0.8 is 140.
therefore, 112 is 80% of 140

(-7x² + 3) + (4x² + 2x - 1)
-7x² + 3 + 4x² + 2x - 1
(-7x² + 4x²) + (3 - 1) + 2x collect like terms
-3x² + 2x + 2
hope this helps, God bless!
