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
A = 30.25pi. PLS GIVE BRAINLIEST
Step-by-step explanation:
so if circumference is 11, and formula for circumference is 2pi*r, we can work backwards to find the radius.
Radius: 11pi/2 = 5.5pi = 5.5 is radius
Area = pi * r^2
so Area = pi*5.5^2
so A = 30.25pi left in terms of pi
Step-by-step explanation:
first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.
You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.
I HOPE THIS HELPS!!!
