Answer:
This is a 25% decrease
Step-by-step explanation:
percent change = (old - new)/old * 100 %
The new price is 15
The old price is 20
Since the new price is less than the old price, it is a decrease
percent change = (20-15)/20 * 100 %
= 5/20 * 100%
=.25 * 100%
= 25%
This is a 25% decrease

Answer:
2.7
Step-by-step explanation:
15% of 18.00 is 2.7
STEP 1
Equation at the end of step
((14 • (x2)) - 7xy) - (3•72y2)
Equation at the end of step 2
((2•7x2) - 7xy) - (3•72y2)
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
14x2 - 7xy - 147y2 = 7 • (2x2 - xy - 21y2)
Trying to factor a multi variable polynomial :
4.2 Factoring 2x2 - xy - 21y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x - 7y)•(x + 3y)
