Step-by-step explanation:
The student hasn't finished the factoring yet.
<u>He still needs the step:</u>
<u>The next step:</u>
- 0 = 2x + 5, 0 = x + 1
- x = - 2.5, x = - 1
The answer is 1/2 in fraction form because 0.5 is half of 1
2(30)=60+30=90. thats a right angle which is 90 degrees so the answer is 30
