Percent change = (new number - old number)/(old number) * 100
percent change = (54 - 48)/(48) * 100 = 6/48 * 100 = 0.125 * 100 = 12.5%
Z - 7 = 8
subtract 7 from both sides
z = 15
hope this helped!
X + (4x+15) = 180
5x+15=180
5x=165
x=33
4(33)+15=147. (Or you could subtract 33 from 180)
Check answer: 33+147=180 yes
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is
.
We need to find the factor of this trinomial.

The factors of
is (x-2) and (x-8).
So, the factor of
is (x-8). Hence, the correct option is (B).
