Solve for x.
(3x+1)2-100=0
(3x+1)2=100
3x+1=100/2
3x=50-1
x=49/3
x=16.33333
Hope that helps. If you have any other questions feel free to ask me
1.5(3x+4)+0.25(6x+8)

Step-by-step explanation:
Answer:
The Correct Statement is
• Use the distance formula to prove the lengths of the opposite sides are the same.
Step-by-step explanation:
The statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent is,
• Use the distance formula to prove the lengths of the opposite sides are the same.
Distance Formula is given by

For Parallel Lines:
Use the slope formula to prove the slopes of the opposite sides are the same.
For Perpendicular Lines:
Use the slope formula to prove the slopes of the opposite sides are opposite reciprocals.
I added a screenshot with the complete question along with its diagram
<u><em>Answer:</em></u>∠1 = 163°
<u><em>Explanation:</em></u><u>1- getting angle 2:</u>We know that ∠2 and the 17° form a straight angle. This means that their sum is 180°.
Therefore:
180 = 17 + ∠2
∠2 = 180 - 17
∠2 = 163°
<u>2- getting angle 1:</u>We are given that lines a and b are parallel.
This means that ∠1 and ∠2 are alternating angles which means that they are equal in measurement.
We have calculated that ∠2 = 163°
This means that:
∠1 = 163°
Hope this helps :)
