Step-by-step explanation:
Use a version of the AC Method.
A
=
3
, B
=5
, C
=
12
Since the sign on the constant term is −
, look for a pair of factors of A
C
=
36 whose difference is B
=
5
The pair 4
, 9 works.
Now use that pair to split the middle term, then factor by grouping:
3
x
2
+
5
x
−
12 =
3
x
−
4
x
+
9
x
−
12
=
(
3
x
2
−
4
x
)
+
(
9
x
−
12
) =
x (
3
x
−
4
)
+
3
(
3
x
−
4
)
Answer:c
Step-by-step explanation:
The raised price represents 110% of the original price (100% plus the extra 10%)
A percentage is converted into a decimal multiplier by dividing by 100:
To clarify the final stage, consider this (where
is the original price):
From here, basic algebraic rules make solving for
easy:
Therefore the original price of a ticket was $175
Original equation: -4(x + 1) + 2
Distribute the -4 through the values in the parenthesis: -4(x) + -4(1) + 2
Simplify: -4x - 4 + 2
Combine like terms: -4x - 2
-4x - 2
Hope this helps!! :)
Answer:
32
Step-by-step explanation:
