Either if the shape have 3 sides or all the angles add up to 180 degrees
Answer:
97
Step-by-step explanation: 65+43=108
108-11=97
For this case we have the following polynomials:

To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
Note: see attached image for the solution.
Answer:
Step-by-step explanation:
a^2+ab+a
a(a+b+1)
The correct answer is B. y + 1 = -1/5 (x + 2)
I got B by putting the numbers in point-slope form which is y - y1 = m ( x - x1 ) so I got: y + 1 = m ( x + 2 )
Then to find m(the slope) I knew if the slope was 5 it would be parallel to y=5x+3 so therefore -1/5 would be perpendicular to the line y=5x=3.
Hope that helps!!
