Answer:
You can get a negative 5 if you subtract -7 minus -2.
Step-by-step explanation:
You would use the equation x + x + 65 + 25 = 180. The equate should be equal to 180 since a triangle is 180 degrees. Then use the equation and solve
2x + 90 = 180
2x = 90
x = 45
Hope you understand!
Answer:
C. 1.87
Step-by-step explanation:
3.5x - 2.8 = -4.67x + 12.5
3.5x + 4.67x = 12.5 + 2.5
8.17x = 15.3
x = 15.3 ÷ 8.17
x = 1.87270501836
So, the closest choice to 1.87270501836 is 1.87, so the answer is C.
Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

Step-by-step explanation:
x - 4 / (x + 5)(x - 1)
let's expand:
x - 4 / x² + 4x - 5
4 - 4 / 16 + 16 - 5 = 0 so answer is 4
