They are supplementary angles. They are located on a straight line, and when added together they will add up to 180 degrees.
we are given with
The polynomial x squared plus 2x minus 24

Hence the required combination is 6x and -4x
The answer will be 6 x 5 x 4 / 3 x 2 x 1, 5 x 4 = 20. Hope this helps
X+ y = 10
2x = 2y+4
2x/2 = 2/2y+4/2
x = y + 2
x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4
x + y =10
x + 4 =10
x +4-4 =10-4
x = 6
Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
Y = 1.55x + 3.70
1.55 x 150 = 232.5
232.5 + 3.70 = 236.2
The answer is C 236.20 hope that helped.
