Answer:

(x^2 + 2x - 21) sq units

Step-by-step explanation:

Area of the shaded region = Area of the larger rectangle - Area of smaller rectangle

Area of the larger region = x(x+2)

Area of the larger region =x^2 + 2x

Area of the smaller rectangle = 3 * 7

Area of the smaller rectangle = 21 sq. units

Area of the shaded region = x^2 + 2x - 21

Hence the required expression is (x^2 + 2x - 21) sq units

Hey salesman needed to settle for Willie he priced at $3500 the first day it was on the market the second he reduced it by 10% w
nataly862011 [7]

Answer:

The price of the four wheeler after with the reduction is $3,150.

Step-by-step explanation:

The original price of the Willa = $3500

The reduction percentage = 10%

Now, 10% of $ 3500 = \frac{10}{100}  \times 3500 = 350

So, the reduction amount is $350.

So, the reduced price of Willa = The original price - The reduced price

= $3500 - $350.  = $3,150.

Hence,  price of the four wheeler after with the reduction is $3,150.

A certain shade of pink is created by adding 3 cups of red paint to 7 cups of white paint.
vazorg [7]

Answer:

7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.

Step-by-step explanation:

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.

You already have the answer! ;)
