Answer:
2y = x+6 is the answer
please mark brainiest
Step-by-step explanation:
2x^3(2x-1) - 3(2x-1)
= (2x^3-3)(2x-1)
Answer:
x= 10, y= 15
Step-by-step explanation:
because alternate interior angles are congruent
8x -10 = 7x
8x -7x = 10
x = 10
because straighht line form 180°
6y+20 +7x = 180
6y +20 +70 = 180
6y = 180 -90
y=90/6 = 30/2 = 15
