Answer:
If line EF was dilated by a scale of 1/2 from the origin to get line E'F', then if line E'F' is dilated by a scale of 2 from the origin, EF is obtained. Also, the length of EF is double than the length of E'F'.
Dilation by a scale of 2 from the origin transforms point (x,y) into (2*x, 2*y)
E'(1,0) -> E(2,0)
F'(1, 3) ->F(2, 6)
length of E'F': 3
length of EF: 6
Answer: x=-17
Step-by-step explanation: Divide by -1 then add 8 to both sides and get (x+9)^3=-512, and the cube root of -512 is -8, so x+9=-8, and subtracting 9 from both sides we get x=-17 as answer.

The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
In the triangle ABC, AB = BC = 8. Triangle ABC is an isosceles triangle and ∠B = ∠C = 30° (base angles are equal).
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
∠A + 30 + 30 = 180
∠A = 120°
The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.
