1.7m^2+2.5m^2-4n-n+6.5
4.2m^2-5n+6.5
So a line is 180 degrees. These angles would equal 180. So 180= w + (3w -28). You add 28 too 180, getting 208. Then divide by the 4w. Leading you to w= 52. Plug into the equations to make sure everything checks out

Answer:
last step is (2x + 5)(2x + 1)
Step-by-step explanation:
4x^2 + 12x + 5
4x^2 + (10 + 2)x + 5
4x^2 + 10x + 2x + 5
2x(2x + 5) +1(2x + 5)
(2x + 5)(2x + 1)
