Answer:
A
Step-by-step explanation:
There need to be more matching points, but there aren't, therefore, its A
Answer:
it is option A
Step-by-step explanation:
Solve using your rules:
180 = 9x + 4x + 37
That means 143 = 13x
Thus x = 11
It may be easier to start from
.. a(x +3)(x -1) = 0
.. a(x^2 +2x -3) = 0
The quadratic
.. ax^2 +bx +c = 0 will have solutions -3 and 1 for ...
.. a ≠ 0
.. b = 2a
.. c = -3a
