Answer:
2a+3+a-2+3a
6a+1
Step-by-step explanation:
The perimeter of a triangle is the measure of side 1 + measure of side 2 + measure of side 3. To find the perimeter of the triangle, simply add these sides together.
(9x - 7w) + (4x + 6y) + (5y + 5w)
Remove the parenthesis
9x - 7w + 4x + 6y + 5y + 5w
Arrange the order so that like terms are together
9x + 4x +6y + 5y -7w + 5w
Combine like terms
13x + 11y - 2w
for the first equation
f(-3) = 34
f(4) = 6
for the 2nd equation
f(-3) = -56
f(4) ÷ 70
