QUADRILATERAL QUAD IS A RECTANGLE FIND THE VALUE OF X AND Y <br><br> DU= 26, QP= 2X +7
grandymaker [24]

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.

QA=DU=26             .... (1)

Diagonals bisect each other.

QP=UP=AP=DP=2x+7      .... (2)

Using (1) and (2) we get

DU=QP+AP

DU=QP+QP

DU=2QP

Substitute given values.

26=2(2x+7)

26=4x+14

26-14=4x

12=4x

Divide both sides by 3.

3=x

Hence, the value of x is 3.

Emily bikes 18 miles in 2 hours. Ella bikes 22 miles in 2.5 hours. Which rate is better?
DaniilM [7]
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.
