To solve these problems. 1. What distance did a car travel that went 70 mph for 6 hours?
2. What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

1) What distance did a car travel that went 70 mph for 6 hours?

Given:

Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.

The car traveled 420 miles in 6 hours.

2) What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

Given:

Formula to find perimeter: 2(L) + 2(B)

Substitute the values into the formula to find the perimeter.

The perimeter of the rectangle is 22 cm.

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 31.27mph
