Answer:
Yeah, D is the right anwser!
Step-by-step explanation:
I would be here for way to long to type up the explanation. And I don't have time to waste.
Take note that the vine was 3.6 ft and now it is 2.1 times as long.
So since is it 2.1 times as long it will be multiplied by 3.6.
3.6(2.1)= 7.56
So it is 7.56 ft long, rounded it is 7.6 ft
39cents would be the answer
Answer:
x = -1, x = 1
Step-by-step explanation:
Factor the equation. (It's a difference of squares, so we know the form will be (a-b)(a+b).)

Test this by FOILing it out, if you're unsure. This is something it can be good to memorize!
Set it equal to 0.

Separate the two parenthetical expressions by the Zero Product Property.

Solve for x!

Answer:
Month since April Number of Ants
0 10,000
1 30,000
2 90,000
3 270,000
4 810,000
Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.
0 months from April = 10,000 * 1 = 10,000 ants
1 month from April = 10,000 * 3 = 30,000 ants
2 months from April = 30,000 * 3 = 90,000 ants
3 months from April = 90,000 * 3 = 270,000 ants
4 months from April = 270,000 * 3 = 810,000
