Answer:
3x^2 - 11x - 4
Step-by-step explanation:
( x - 4 ) ( 3x + 1 )
= 3x^2 + x - 12x - 4
= 3x^2 - 11x - 4

Answer:
∠U = 60°
∠W = 30°
Step-by-step explanation:
The side length ratios are ...
1 : √3 : 2
so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).
The angle measures are ...
m∠U = 60°
m∠W = 30°
[the UW measure is correct]

Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
