Answer:
-2x² + 21x + 27
Step-by-step explanation:
distribute 3 to get:
(6x² + 21x + 12) - 8x² + 15
combine 'like terms' to get:
-2x² + 21x + 27
The percent change would be 36%
<h3>What is percent change?</h3>
Percent increase and percent decrease are measures of percent change, which is the extent to which a variable gains or loses intensity, magnitude, extent, or value.
Given:
4 candy bars = 5$
1 candy bar = 5/4
1 candy bar = 1.25$
Now,
5 candy bars = 4$
1 candy bar =4/5
1 candy bar = 0.8$
% change = (0.8-1.25) / 1.25 *100
= 36%
