Combine like terms. remember to keep the signs.
5x² - 2x² = 3x²
3x - (-6x) = 3x + 6x = 9x
4 - (-3) = 7
3x² + 9x + 7 = Ax² + Bx + C
9 = B, because 9 is in the B's place
9 is your answer
hope this helps

1,100 ft/min * (60 min)/(1 hr) * (1 mile)/(5280 ft) = 12.5 miles/hr
Answer:
y = 102, z = 67
Step-by-step explanation:
The angles 113 and z form a straight angle and are supplementary, thus
z = 180 - 113 = 67
The sum of the 4 interior angles of a quadrilateral = 360°
Sum the interior angles and equate to 360 for y
y + 102 + 89 + 67 = 360, that is
y + 258 = 360 ( subtract258 from both sides )
y = 102
