Percent of change =

Substitute 180 for V2 and 160 for V1
Percent of change =

Solve
Percent of change =

Percent of change = 0.125 x 100
Percent of change = 12.5%
Basically all you’re doing is plugging in the inputs to the equations and see if they’re correct.
5(3)+4(-3)=3 this proves to be true
2(3)-5(-3)=21 not 19
The value of the product expression (-2x-9y²)(-4x-3) is 8x² + 6x + 27y² + 36xy²
<h3>How to evaluate the product?</h3>
The expression is given as:
(-2x-9y²)(-4x-3)
Expand the expression
8x² + 6x + 27y² + 36xy²
Hence, the value of the product expression (-2x-9y²)(-4x-3) is 8x² + 6x + 27y² + 36xy²
