Answer:
The positive solution is 6.
Step-by-step explanation:
x^2 - 6 = 5x (Subtract 5x from both sides)
x^2 -5x - 6 = 0 (We can factor this, so there is no need to use the quadratic formula)
(x - 6)(x + 1) = 0
If the product of the two terms is zero then either one being equal to zero will cause the whole expression to be zero.
The solutions are:
x - 6 = 0 (Add 6 to both sides)
x = 6
x + 1 = 0 (Subtract 1 from both sides)
x = -1
The positive solution is 6.
Answer:
C
Step-by-step explanation:
Since the angles in a triangle add to 180 degrees, the third angle is 180-70-45=65 degrees
