Answer:
equation : 2x + 4 = 3x - 5
X = 9
BC = 22
Answer:
x = 7+√(3), 7-√(3)
Step-by-step explanation:
x^2 - 14x + ___ = -46 + ___
x^2 - 14x + 49 = -46 + 49
(x-7)^2 = 3
√(3) = x-7
x = 7+√(3), 7-√(3)
Even odd even odd, aka D.
I believe you multiply 2 times everything in parenthesis. 2 times x is 2x. 2 times 4 is 8. so that would be 2x + 8.
