Ahouse builder is installing a picture window that is topped with an arch in the shape of a semi-ellipse. the width is 7 feet, and the height is 3 feet. to sketch the arch above the window, the builder uses a string attached to two thumbtacks. approximately where (how far from the center) should the thumbtacks be placed?

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

no this is a nonlinear negative
