<h3><u>The expression that represents the area of the building, in terms of x is:</u></h3>

Area = 240x^2 +360x - 240

<em><u>Solution:</u></em>

Given that,

<em><u>Dimensions of rectangular building:</u></em>

Length = 12x + 24 feet

Width = 20x - 10 feet

<em><u>The area of rectangle is given as:</u></em>

Area\ of\ rectangle = length \times width

<em><u>Substituting the values we get,</u></em>

Area\ of\ rectangle = (12x+24) \times (20x-10)

Multiply both

Area = 12x\times \:20x+12x\left(-10\right)+24\times \:20x+24\left(-10\right)\\\\Area  = 240x^2 -120x + 480x -240\\\\Area = 240x^2 +360x - 240

Thus the expression that represents the area of the building, in terms of x is found

Hey there! :)

Answer:

y = x - 3.

Step-by-step explanation:

Given:

Slope = 1

Point on line: (8, 5)

Plug these into the formula y = mx + b, where:

m = slope

x = x coordinate of point

y = y coordinate of point

5 = 1(8) + b

5 = 8 + b

Subtract both sides by 8:

5 - 8 = 8 -8 + b

-3 = b

Rewrite the equation:

y = x - 3.

Rolando's Labrador retriever had 12 puppies. Eight of her puppies were yellow labs and the rest were black labs. What is the rat
natta225 [31]

Answer:

1:2

Step-by-step explanation:

There are 12 total puppies. To find the number of black puppies, we have to subtract the yellow from the total. So:

12 - 8 = 4

There are 4 black puppies. Now we put the black puppies in ratio to yellow puppies:

4:8

Then simplify (divide both sides by 4):

1:2
