The answer would be C because he did not correct his mistakes that he had made
Make it an improper fraction with two as the denominator, and you'll get 9/2. There are 9 halves in 4 1/2 meters
1. x^2 + x - 90
2. (x+10)(x-1)
3. x= -10 and 1
Answer:
x = 12
Step-by-step explanation:
Complementary angles add up to have a sum of 90 degrees. We can create an equation and solve for x.
3x + 6x - 18 = 90
~Simplify
9x - 18 = 90
~Add 18 to both sides
9x = 108
~Divide 9 to both sides
x = 12
Best of Luck!
