Answer:
Step-by-step explanation:
(x - 2)(x² + 7x + 4) = x(x² + 7x + 4) - 2*(x² + 7x + 4)
= x*x² + x*7x + 4*x - 2*x² -2* 7x -2* 4
= x³ + 7x² + 4x - 2x² -14x -8
= x³ + <u>7x² - 2x²</u> <u>+ 4x - 14x</u> - 8
= x³ + 5x² - 10x - 8
Answer:
cubic binomial is your answer
Answer:
Dude why did you do this to us it's too hard
Step-by-step explanation:
P.S. It' 6
Complimentary angles add up to 90 degrees
x + y = 90
x = y + 8
y + 8 + y = 90
2y + 8 = 90
2y = 90 - 8
2y = 82
y = 82/2
y = 41
x = y + 8
x = 41 + 8
x = 49
so ur angles are : 41 and 49
