Answer:
2a (3-4a)
Step-by-step explanation:
(2a+1)-4a(2a+1)+4a
2a+1-8a²-1+4a
= 2a+4a-8a²
=6a-8a²
= 2a(3-4a)
Is the second paragraph meant to throw you off??? Because the answer to the question does not rely on the information based from the second paragraph...
Anyway, we know that the turtle started from (0, 0) and moved to (10, 8). Let's assume that (0, 0) is (x1, y1), and that (10, 8) is (x2, y2) for the sake of calculations.
To find how far the turtle moved to the right (along the x-axis) we take x1 from x2:
x2 - x1 = 10 - 0
= 10 = x2
***this is the "run"
To find how far the turtle moved upwards (along the y-axis) we take y1 from y2:
y2 - y1 = 8 - 0
= 8 = y2
***this is the "rise"
Notice that when something moves away from the origin the distance it traveled along the x-axis and y-axis is the same as its final position (or coordinates to where it traveled to).
Therefore, the,
slope = rise / run
= x2 / y2
= 10 / 8
= 5 / 4 (preferable for use)
= 1.25
I can't really answer that. Sorry. But I know a YouTube account that can help you. Search up L. Moon and it will show you a list of videos.
1. First do 18,000 times .20 to get 3,600. Next minus 18,000 by 3,600 and you get $14,400 which is the answer.
2. First do 125 times .15 to get 18.75. Next minus 125 minus 18.75 to get 106.25. Then you do 106.25 times .05 to get 5.31. Finally, add 5.31 to to 106.25 and you get $111.56.
3. 17/39 as a decimal is .4358
4. First you do 45 times .06 to get 2.7. Finally you add 2.7 back onto 45 to get $47.7
5. true (i’m 99% sure on this question)
hope dis helped
