Answer:
3x+2
Step-by-step explanation:
-First, we can represent the number of cookies using x.
-3 times x is 3x.
-Two cookies more tells you that you will be adding 2 to your equation
Goodluck!
Hey there! :D
Let's keep the fraction 5/7 in mind. We should be able to reduce everything to 5/7.
15:21 (divide both by 3) you get 5:7. That is equivalent.
10 to 14. Divide both by 2. 5 to 7. That is equivalent.
The correct answer is 28/20. That is not equivalent.
I hope this helps!

Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63
Answer:
Domain:
[-5,-2) U (-2,3.5) U (3.5,5]
Range:
[-3 0) U (0,5]
It is not a function because x = 1 has two different outputs (3 & 5)
When you want to write a polynomial, you should write the term with the highest degree first.
Here, it should go like this: d^3 + d^2 - d + 3
This means that the term which should be written first is the cubic term.
