I need alot of help with f(x) = x2 + 9x – 36 because i have an assignment due later tonight and it will bring my grade down majorly

so if the x2 is x squared and you are trying to find the values of x where f(x) is 0 then they are -12 and 3

Step-by-step explanation:

we can factor these into (x+12)(x-3)

in order for (x+12)(x-3) to be 0 then one of them has to be 0

first is (x+12) = 0 so x is -12

second is (x-3) = 0 so x is 3

the correct answer is the second option

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
