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.
Answer:
true
Step-by-step explanation:
Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
Fallow the steps in the picture
3a² - 2a - 4 + 2a -3a² + 5
Put all the like terms together
= 3a² -3a² + 2a - 2a + 5 - 4
Combine like terms
= 1
