I believe its c! Hope this helps :>
Answer:
-6
Step-by-step explanation:
Plug in x = 3 in the equation: 3(3 - 4) + 2(3) - (3)^2
Now simplify with order of operations:
3(3 - 4) = -3
2(3) = 6
-(3)^2 = -9
-3 + 6 - 9 = -6
x^2 + 10x + 4 = 0
you can use the quadratic formula to solve:
a = 1, b = 10, c = 4
x= −b ± √b^2 −4ac / 2a
x = -10 ± √(10)2 − 4(1)(4) / 2(1)
x = -10 ± √84 / 2
x = -0.42 or -9.58
Decreased by: ___ -
difference: (___ - ___)
27 - (x - 3) is an accurate model of this situation.
