Really confused and am on final attempt!

C

Step-by-step explanation:

the legs of a 30-60-90 triangle are 1 and , while the hypotenuse is 2.

the ratio of the legs is therefore 1 : → C

for b its (t) and c its (d)

step-by-step explanation:

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
