Answer:
x^2+7x+12
Step-by-step explanation:
(x+3) (x+4)
FOIL
first: x*x = x^2
outer: 4x
inner: 3x
last: 3*4 =12
Add them together
x^2 +4x+3x+12
x^2+7x+12
I believe using the equation v=lwh the answer would be 420ft^3.

The answer is C) 160.
We know this because if mA = 50, we know that mC must also be 50. This is due to the fact that AB = BC. This leaves us with mB as 80 since the angles of a triangle always have to equal 180.
Now knowing this, it is easy to find the arc lengths in degrees. When you have a transcribed triangle, all we are going to do here is double the angle of the triangle to get the arc measure.
mB = 80
80*2 = 160
