Solve for x by factorising.
3x²+4x= 4

Step-by-step explanation:

3x^2+4x-4=0 (we move 4 to the other side to factor)

(3x-2)(x+2)

^think of 2 numbers that when you multiply it will be -4 and when you multiply one of it to 3x and add to the other it will be 4x.

Recheck:

-2(2)= -4 (correct)

-2x+6x=4x (correct)

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

a 360 degree rotation
