Answer is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 20.2
B. Y=2x
Which mean each 1 cost $2
If you buy 2 then it cost $4
I believe this is correct answer
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
A. Opposite sides are parallel is correct, because if opposite sides were not parallel, it would be a trapezoid, not a parallelogram.
