The difference in elevation of a helicopter and a submarine is 18 1/2 meters. The elevation of the submarine is −7 3/4 meters. Write and solve an equation to find the elevation h (in meters) of the helicopter. An equation is ___ =18 1/2.

The elevation of the helicopter is ___ meters.

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

each side has a different length.
