Answer:
5x²- 1.8
Step-by-step explanation:
roots are -3 and 3, put them in brackets
(x - 3)(x + 3)
x² + 3x - 3x - 9
x² - 9
5x = -9
x = -1.8
5x² - 1.8
just to check:
5x² - 1.8
x² - 9
(x - 3)(x - 3)
x = -3 and 3.
The answer is c, because only $1.25 would be gone each week. in 3.82 only 4 dollars would be missing out of 16.

It's a 90 degree rotation since it only moves one quadrant up clockwise
Angle ADC and EDG are congruent(vertical angles)
Same side interior angles are =180
2x+4x-30=180
6x-30=180
6x=210
x=35
CDG is congruent to DGH(alternate interior)
4x-30
4(35)-30
140-30
=110
If the whole rectangle is green it is certain
if none of the rectangle is green it is impossible
if the green takes up half or over half it is likely
if the green takes up less than half it is unlikely
