We have been given the function f(x) = 60x^2 - 57x -18

Now, the given potential roots are -6/5, -1/4, 3, 6. In order to find the actual root of this function, we substitute the root in the given function and if we get zero, then that would be the actual zero.

f(-6/5)=60(-6/5)^2-55\cdot\frac{-6}{5} -18= \frac{684}{5}\neq 0\\\\f(-1/4)=60(-1/4)^2-55\cdot\frac{-1}{4} -18=0\\\\\\f(3)=60(3)^2-57(3)-18=351\neq 0\\\\f(6)=60(6)^2-57(6)-18=1800\neq 0

We got zero for the value -1/4.

Hence, the actual root of f(x) is -1/4.

B is the correct option.

Roman55 [17]

Answer:

∠DCE≅∠BAE

Step-by-step explanation:

CPCTC is basically used at or near the end of a proof which asks the student to show that two angles or two sides are congruent. Corresponding means they're in the same position in the 2 triangles

two side CE and AE are equivillant in the expression

hence

∠DCE≅∠BAE is right option.
