Answer:
x = 0 or
Step-by-step explanation:
We have the quadratic equation of variable x and we have to solve the equation using the square root property.
Now, we have x(3x - 17) = 0
⇒ 3x² - 17x = 0
⇒
⇒
⇒
Now,square rooting both sides we get,
Therefore, either x = 0 or (Answer)
Answer:
C.) 14
Step-by-step explanation:
Look at the triangle: angles b and c have the same arch, so they are congruent.
In a triangle, if two angles are congruent, then the triangle is isosceles, having two equal sides.
The sides opposite the congruent angles are congruent:
∠B → opposite side → AC
∠C → opposite side → AB
The sides AB and AC are equal. Make an equation:
Simplify the equation, solving for x. Add 7 to both sides:
Subtract 2x from both sides:
The value of x is 7. Insert the value of x into the given length of AC:
Simplify multiplication:
Subtract:
Therefore, the length of the line segment AC is 14.
