Answer:
(f+g)(x)= 2x²+2x-2
Step-by-step explanation:
-x²+6x-1+3x²-4x-1 can be found by combining like terms.
2x²+2x-2
Answer:
13 m
Step-by-step explanation:
The ladder forms a right triangle with the wall that has legs of 5 and 12. We need to solve for the length of the ladder, which in this case, is the hypotenuse of the right triangle. You could use the Pythagorean Theorem but there's an easier way to do this. We can use the 5 - 12 - 13 Pythagorean triple so we know that the length of the ladder is 13 m.
Answer:
m 1 = 45 degrees because 1 and the angle measuring 135 degrees are supplementary angles.
m 2 = 95 degrees because 2 and the angle measuring 95 degrees are vertical angles.
m 3 = 40 degrees because 1, 2, and 3 form a triangle

Answer:
B
Step-by-step explanation:
6x + 30 + 4x = 10(x+3)
10x + 30 = 10x + 30
0 = 0
