Add seven to both sides of the equal sign. Now you have 3x= -18
Then divide by three on each side. Now you have x= -6
Then plug it in.
-6^2-6(-6)+9
The answer to that is 9
Answer:
Step-by-step explanation:
<u>x is side of right triangle with other sides:</u>
<u>Then x is:</u>
- x² = √20² - 4²
- x² = 4
- x = 2
2 miles: 1/2 hour
? mile: 1 hour
(2÷1/2)mi/h or B is your final answer. Hope it help!
Shape A is congruent to shape D because a 180° rotation about the origin and then a translation 2 units right maps shape A onto it.
Shape B is congruent to shape E because a 90° clockwise rotation about the origin and then a translation 1 unit left maps shape B onto it.
