Answer:
The value of x is 3.
Step-by-step explanation:
Consider the below figure attached with this question.
Given: Quadrilateral QUAD is a rectangle, DU=26 and QP=2x+7.
We need to find the value of x.
Diagonals of a rectangle are equal.
.... (1)
Diagonals bisect each other.
.... (2)
Using (1) and (2) we get
Substitute given values.
Divide both sides by 3.

Hence, the value of x is 3.
I thing it is B...plz tell me if I am right but I think I am
By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
X²-2x=x
x^2-2x-x=0
x^2-3x=0
x^2=3x
x(x-3)
x=3 x=0
