Answer:
x=27
Step-by-step explanation:
Triangle angle =180 degrees
180=2x+5+x+17+3x-4
180=6x+18
(180-18)/6=x
x=27

Answer:

Step-by-step explanation:
The first step is to find the GCF. Here, it's 3.

Then, you factor the polynomial in the parenthesis.
To find the factors, you will need to find 2 numbers that add to -7, and multiply to 10. -2 and -5 add to -7 and multiply to 10. Now, replace -7a with the factors.

This of this polynomial as 2 problems.

Then, factor again.


Then, you keep the factors in parenthesis, and combine the numbers on the outside.

Since, there are 2 of the same factor, you only need one.

BUT REMEMBER!! In the very beginning, we had a 3 that we took out, we STILL need to add that to the final answer. The <u>final answer</u> is:

Answer:
answer is option A
A, 4+12>6✓
12+6>4✓
4+6>12×
because sum of two sides lengths ina a triangle should greater than the other side's length
