Answer:
X^2-x-12
Step-by-step explanation:
FOIL
First, Outside, Inside, Last
First: X*X=X^2
Outside: x*-4=-4x
Inside: x*3=3x
Last:3*-4=-12
All together: X^2-4x+3x-12
Simplify: X^2-x-12
For #1. 3x + x +7 = 180 degrees
4x + 7 = 180
4x = 173
so x = 43.25
For #2. 2x + 5 = 110 degrees
2x = 105
so x = 52.5
For #3. 1 and 3, 2 and 4, 5 and 8, 6 and 7.

27 Yards will be ran in 15 Seconds
Convert 27 Yards into Feet.
27 Yards = 81 Feet
Answer:
24.03 feet
Step-by-step explanation:
tan(59⁰)=40/x
x=40/tan(59°)
x=24.03
