Answer:
Step-by-step explanation:
To solve this problem, you have to combine like terms of x and b from one side of the equation.
<h3>4x+3(2x+5b)-4b-2x+6</h3><u>Combine like terms.</u>
3(2x+5b)+4x-2x-4b+6
<u>Solve.</u>
4x-2x=2x
Rewrite the problem down.
3(2x+5b)+2x-4b+6
Expand the form.
Use a distributive property.
<u>Distributive property:</u>
A(B+C)=AB+AC
3(2x+5b)
<u>Multiply.</u>
3*2x=6x
3*5b=15b
<u>Rewrite the problem.</u>
6x+15b
6x+15b+2x-4b+6
<u>Combine like terms.</u>
6x+2x+15b-4b+6
<u>Add the numbers from left to right.</u>
6x+2x=8x
8x+15b-4b+6
<u>Then, you add again.</u>
15b-4b=11b
<u>= 8x+11b+6</u>
- <u>Therefore, the final answer is 8x+11b+6.</u>

Answer:
E. 4x -180
Step-by-step explanation:
Angles QPB and RAP are corresponding, so congruent. Angles QPR and ARP are alternate interior angles, so congruent. Triangles BQP and PQR are isosceles, so angle PBQ ≅ angle QPB and angle RQP = 180-2x.
The total of angles RQP and RQC is angle PQC, an external angle to triangle PQB. We know the exterior angle is equal to the sum of the remote interior angles. That means ...
angle PQC = angle QPB +angle QBP
y +(180 -2x) = x + x
y = 4x -180 . . . . . . . . . . . subtract (180-2x) from both sides
