since 3c is not equal to 2c, this means that the expressions are not equal
Answer:
(5a+4c)(2a-b)
Explanation:
Given the expression:

First, group the expression into two:

• In the first group, 5a is a common factor.
,
• In the second group, 4c is a common factor.
Factor these out by dividing each term by the GCF of each group.

Since the terms inside the brackets are the same, combine:

The angle measures are 60, 60, 60
Answer:
x = 6 or x = -15
Step-by-step explanation:
x2+9x−90=0
Step 1: Factor left side of equation.
(x−6) (x+15)=0
x−6=0
x+15=0
x=6
x=−15
x=6
x=−15
