Follow these steps and you should get your answer its not the same questions but it should help
The answer to the problem is as follows:
These two polynomials are 5x^2 + 3x + 5 and 3x^2 +2x + 2:
Subtracting the second expression from the first:
<span>5x^2 + 3x + 5
- (3x^2 +2x + 2)
</span>____________
<span>2x2 + x + 3 <------------- The difference

Answer:
≈ 1833
Step-by-step explanation:
To find ratio of proton mass to electron mass, we have to divide.
The numbers are given in <em>scientific notation</em>.
Let a number be
and another be
, when we divide, we will follow the rule shown below:

Now, we use the information given to find the ratio:

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
Answer:
Price of Caleb's groceries before tax = $64
Step-by-step explanation:
Let the price of groceries before tax be =$ 
Sales tax charged = $1.60
Sales tax rate =2.5%
Sales tax charged in terms of
will be = 2.5% of the Original price of grocery =
So, we have,

Dividing both sides by 

∴ 
∴ Price of Caleb's groceries before tax = $64
Answer:
(6,-6)
Step-by-step explanation:
well if you count over to the right 6 and down 6 that points would be
(6,-6)
(-2.5,6.1)(-2.5,3.1).....notice how ur x values are the same. This means that u have a vertical line which has an undefined slope.
IF ur y values would have been the same, u would have had a horizontal line which has a 0 slope.
