Answer:

x = 32

Step-by-step explanation:

Add 7 to both sides

\sqrt{2x} -7+7=1+7

Simplify

-7 + 7 = 0 and 1 + 7 = 8 because of this now \sqrt{2x} =8

Square both sides

2x = 64

Slove 2x = 64

64 ÷ 2 = 32 = x

Find YW. YW = _<br><br> I just need the answer for YW no explanation needed.
KATRIN_1 [288]

Answer:

YW=20\ units

Step-by-step explanation:

we know that

In a parallelogram the diagonals bisect each other

The figure XYZW is a parallelogram

so

VW=VY

VX=VZ

<em>Find the value of b</em>

VW=VY

substitute the given values

b+8=5b

solve for b

5b-b=8\\4b=8\\b=2

Find the length of YW

YW=YV+VW ----> by addition segment postulate

YW=5b+b+8

substitute the value of b

YW=6(2)+8=20\ units
