Answer:
It helps because it gets you thinking. Personally, it would motivate me because that process itself is very helpful. Brainstorm will get you your idea, you can decide if you want to do it or not, then you work on it, and because you have the right attitude towards whatever you are working on, you'll enjoy it!
Answer: C O R R E C T
Step-by-step explanation:
Answer:
Option A m(3m + 4)(3m - 4)
Step-by-step explanation:
we have
Factor m
![m[9m^{2}-16]](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D)
Apply difference of squares
we know that
![[9m^{2}-16]=(3m+4)(3m-4)](https://tex.z-dn.net/?f=%5B9m%5E%7B2%7D-16%5D%3D%283m%2B4%29%283m-4%29)
substitute
![m[9m^{2}-16]=m(3m+4)(3m-4)](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D%3Dm%283m%2B4%29%283m-4%29)
Answer:
Charlene cannot bring 20 books because the weight of her luggage will be more than the permitted weight. She can only bring at most 15 books
We can represent this inequality as:
5 + 3x ≤ 50
Step-by-step explanation:
Whenever we are dealing with inequalities, a good trick is to solve the problem using an "equals to" sign and change it to the "inequality" sign at the last minute.
Let us assume that she carries x books.
The weight of her suitcase + the weight of all the 3-pound books must not be more than 50 pounds.
We can represent this inequality as:
5 + 3x ≤ 50
having said this, to find the value of x, which is the maximum number of books she is allowed to carry.
To do this, we replace the inequality sign with the "equals to" sign
5 + 3x = 50
from this, we have that
3x = 45;
x = 45/3
x = 15 books
From this, we can see that Charlene is not allowed to carry more than 15 books.
i.e x ≤ 15
Charlene cannot bring 20 books because the weight of her luggage will be more than the permitted weight. She can only bring at most 15 books
