Answer:
x=2
Step-by-step explanation:
Since the angles are equal, the side lengths are equal (isosceles triangle)
12 =6x
Divide by 6
12/6 = 6x/6
2= x
Answer: x = -16
Step-by-step explanation:
3x - 11 = -x - 75 then solve. see photo attached for work.
For indicies, the numerator is the normal power, and the denominator is a root as such. So 1/2 would be square root, 1/3 would be cube root, 1/4 would be 4th root and so on.
So, 64^(1/3) is the third root of 64, which is equal to 4.
Determine the number of solutions using the discriminant D=b^2-4ac
D=m^2-4•3•(-3)
Calculate the product D=m^2+36
Since D > 0 for any value of m
The quadratic equation has 2 real roots.
