Answer:

The answer to your question is      3a²

Step-by-step explanation:

The correct Polynomial is

                          (4a² + b) − (a² + b)

Use the law of signs

                           4a² + b - a² - b

Use the associative property for like terms

                          (4a² - a²) + (b - b)

Simplify like terms

                          4a² - a² = 3a²

                            b - b = 0

Write the result

                             3a²

Answer:

Philomena would make more than $14.06 interest in the second month

Step-by-step explanation:

We are not told how much Philomena put initially, but what we are told is that she has more now as she has been making interests.

This means that if the percent interest remains the same, the amount will definitely have to be more.

For example, let's say we had $10 and we had 10% interest that means we now add $1 to make $11. Since we now have $11, 10 percent of that is $1.1. so now we have $11 + $1.1 = $12.1 which is more than $11.

Thus,Philomena would make more than $14.06 interest in the second month.

Step-by-step explanation:

It is given that,

Miguel made 80 on his Math test. He made 95 in last week's Math test.

We need to find the percent change on his scores. It can be calculated as follows :

\%=\dfrac{\text{original score-initial score}}{\text{original socre}}}\times 100\\\\\%=\dfrac{95-80}{95}\times 100\\\\\%=15.78\%

So, there is a percent change of 15.78%.
