Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23
3(23) - 19 = 50
50 + y = 180
180 - 50 = y
y = 130
I just got free points. Thank you.
The value of x that makes lines a and b parallel is 76°.
This is because when two parallel lines are cut by a
transversal, the alternate angles formed by the transversal are equal. In the
figure below, the angle x is an alternative interior angle to the angle
measured 76°, so they are equal. That is, x = 76° (provided that line a is parallel to line b)

Answer:
option 3 : (2x - 7 )
Step-by-step explanation:
ax + bx = x(a+ b)
a(x+ y) + b(x+y) = (x+y)(a+b)
![(3x - 8 ) ( 2x + 5) - (x + 1)(2x + 5)\\\\(2x+5)[ (3x - 8) - (x+1) ]](https://tex.z-dn.net/?f=%283x%20-%208%20%29%20%28%202x%20%2B%205%29%20-%20%28x%20%2B%201%29%282x%20%2B%205%29%5C%5C%5C%5C%282x%2B5%29%5B%20%283x%20-%208%29%20-%20%28x%2B1%29%20%5D)
[ (2x + 5) is common is both terms ]
Therefore , the binomial is ( 2x - 7)
