Answer:

3x² - 2x - 16

Step-by-step explanation:

Shaded region is the difference of the areas of the rectangles

Area of the bigger rectangle:

A = 2x(2x + 4) = 4x + 8x

Area of the smaller rectangle:

A = (x + 2)(x + 8) = x² + 10x + 16

Area of shaded region:

A = 4x² + 8x - x² - 10x - 16 = 3x² - 2x - 16

ratio of a rectangle's length to its width is 4:7. If the longer side is 31.5in., find the width, the perimeter, and the area of

Nikitich [7]

Answer:

Step-by-step explanation:

Ratio of length : width = 4 : 7

Length = 4x

Width = 7x

Longer side = 31.5 in

⇒ 7x = 31.5

Divide both sides by 7

x = 31.5/7

x = 4.5

length = 4x

= 4*4.5

l = 18 in

width = 31.5

w = 31.5 in

$\boxed{ \text {Perimeter of rectangle }= 2*l + 2*w}$

= 2*18 + 2*31.5

= 36 + 63

= 99 in

$\boxed{ \text{Area of rectangle = l*w}}$

= 18*31.5

= 567 in²

You wish to borrow $8000 for debt consolidation. The bank's interest rate for a personal loan is 7.2%. What is your monthly paym

Lisa [10]

<h3>The monthly payment is $242.44 for loan to paid off in 3 years.</h3>

Step-by-step explanation:

The amount borrowed = Principal = $8000

The rate of interest = 7.2%

Time (T) = 3 years

Now, Simple Interest = $\frac{P\times R \times T}{100}$

$\implies SI = \frac{8000 \times 7.2 \times 3}{100} = 1,728$

So, the total interest = $1728

Now, Amount to be paid = Principal + Interest

⇒ A = $8000 + $1728 = $8728

Also, 1 year = 12 months

⇒ 3 years = 3 x 12 months = 36 months

So, total amount to be paid in 36 months is $8728.

⇒The amount to be paid in 1 month is $(\frac{8728}{36} ) = 242.44$

Hence, the monthly payment is $242.44 if loan is to paid off in 3 years.
