Step-by-step explanation:
10x² + 11x − 6 = 0
10x² + 15x – 4x – 6 = 0
5x(2x + 3) – 2(2x + 3) = 0
(2x + 3) (5x – 2)
It be 81.
You have to take half of -18 which is -9, and square that, which is 81.
x + 47 = 92. <--- x represents the number of 3rd graders
x +47-47 = 92-47
x=45
There are 45 third grader. Hope this helped!
