Answer:
The original cost is $350
Step-by-step explanation:
Let's assume
original cost of computer is x
There is a 10% off sale on laptop computers
So, amount saved is

now, we are given
someone saves $35 on a laptop
so, we can set them equal
and then we can solve for x

we can divide both sides by 0.10
and we get

So,
The original cost is $350

B or E are most likely the answer but I’m not too sure
The factorization of 12a^3b^2 +18a²b^2 – 12ab^2 is 
<u>Solution:</u>
Given, expression is 
We have to factorize the given expression completely.
Now, take the expression

Taking
as common term,

Taking "a" as common term,

Taking "6" as common term,

Splitting "3a" as "4a - a" we get,


Hence, the factored form of given expression is 
Answer:
The average rate of change is 8.
Step-by-step explanation:
The formula to calculate the average rate of change of a function F(x) is:

In this case, F(x) = 
a=2 and b=4
You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.
In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:
F(b) = 
F(a) = 

The answer is 8.
