The cruise control feature on a car is designed to maintain a set speed. if the car’s actual speed never varies by more than four mph, what is the difference between the maximum and minimum speed of the car when cruise control is used?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
