Step-by-step explanation:

What's the square root of x^2?

That's x

What's the square root of 49

That's 7

And what makes 14?

7 + 7 = 14

So therefore the answer is (x + 7) (x + 7)

Answer:

The middle number is 14 and the last number is 49.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 14

Multiply together to get 49

Can you think of the two numbers?

Try 7 and 7:

7+7 = 14

7*7 = 49

Fill in the blanks in

(x+_)(x+_)

with 7 and 7 to get...

(x+7)(x+7)

Answer:

(x+7)(x+7)

Jennifer recently finished paying off her $30,000 fixed-rate student loan. She paid $303.73 per month for 10 years to

kaheart [24]

Answer:

$6,447.60

Step-by-step explanation:

Since Jennifer's monthly payment was $303.73 and she paid this amount each month for 10 years, multiply the monthly payment by the number of months in 10 years, 120, to determine the total amount that she paid.

$303.73×120=$36,447.60

Now, subtract the stated amount of the loan from the total amount paid to find the amount of interest that was paid.

$36,447.60−$30,000=$6,447.60

Therefore, Jennifer paid $6,447.60 in interest through the duration of the loan.

Aiden estimates the length is 7.2 but it’s 6.5 what’s the percent error

IrinaVladis [17]

Percent error is 10.7%

Step-by-step explanation:

We need to find the percent error:

We are given:

Estimate value = 7.2

Actual value = 6.5

Percent Error=?

The formula used is:

$Percent\,\,Error=\frac{Estimate\,\,value-Actual\,\,value}{Actual\,\,value}\times100\\$

Putting values:

$Percent\,\,Error=\frac{7.2-6.5}{6.5}\times100\\Percent\,\,Error=\frac{0.7}{6.5}\times100\\Percent\,\,Error=0.107\times100\\Percent\,\,Error=10.7%\\$

So, Percent error is 10.7%
