222-35+75 is 262 and 70+7,777 is 7,847
Answer:
x^2 -17x+72
Step-by-step explanation:
(x – 8) (x – 9)
FOIL
first x*x =x^2
outer -9*x = -9x
inner -8*x = -8x
last = -9*-8 = 72
Add them together
x^2 -9x-8x+72
x^2 -17x+72
Answer: here
Step-by-step explanation:
Acute Angle - An angle less than 90 degrees. Right Angle - An angle that is exactly 90 degrees. Obtuse Angle - An angle more than 90 degrees and less than 180 degrees. Straight Angle - An angle that is exactly 180 degrees. Reflex Angle - An angle greater than 180 degrees and less than 360 degrees.
The x-intercept is found by solving the equation for y=0. Doing that, we get ...
0 = x+1 . . . . .put 0 where y is in the equation
-1 = x . . . . . . subtract 1 from both sides
Then the x-intercept is ...
(x, y) = (-1, 0) . . . . . . corresponds to the second selection
