Answer:
3x2 + 4x − 4. A (x + 4) B(3x + 2) C(3x − 2) D(x − 2)
Answer:
(2,-4)
Step-by-step explanation:
Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k).
then cross multiply which gives you
divide each side by 30 to make the x by itself
which gives you the answer x=40
