Afarmer leans a 12-ft ladder against a barn. the base of the ladder is 3ft from the barn. to the nearest tenth, how high on the barn does the ladder reach? f. 9.2ft g. 10.8ft h.11.6ft i.13.4ft

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
