Which of the following are solutions to the equation below? Check all that apply.
x2 + 4x-9 = x + 1
A. 2
B. 4
C. -7
D. -5
E. -3
F. -4

A.2

Step-by-step explanation:

X is equal to 2

If you plug in 2 for X both sides will equal each-other

2(2) + 4(2)-9 = (2) + 1

4 + 8 - 9 = 3

12-9 = 3

3 = 3

Therefore X is equal to 2

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

2nd one in the first row is correct
