Can somebody please help me with this?

x = 3

Solution:

Given UVWX is a parallelogram.

UV, VW, XW, UX are sides of a parallelogram.

UW and XV are diagonals of a parallelogram.

VX = 14 and BX = x + 4

Property of parallelogram:

Diagonals of a parallelogram bisect each other.

⇒ VB = BX

⇒ VX = VB + BX

⇒ VX = BX + BX (since VB = BX)

⇒ VX = 2 BX

⇒ 14 = 2(x + 4)

⇒ 14 = 2x + 8

Subtract 8 from both sides of the equation, we get

⇒ 14 – 8 = 2x + 8 – 8

⇒ 6 = 2x

Divide by 2 on both sides of the equation, we get

⇒ 3 = x

⇒ x = 3

Hence the value of x is 3.

you answer is a

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
