Answer:

Area: 240x² - 72x - 240

Perimeter: 64x + 28

Dimensions: <em>l</em> = 60, <em>w</em> = 50

Step-by-step explanation:

<u>For Area:</u>

<u>Multiply length by width.</u>

(12x + 24) • (20x - 10)

<u>Let's foil this out (first, outer, inner, last)</u>

240x² - 120x + 48x - 240

<u>Simplify.</u>

240x² - 72x - 240

<u>For Perimeter</u>

Remember that a rectangle has <em>two</em> sets of matching parallel sides.

<u>Let's write out our equation.</u>

2(12x + 24) + 2(20x - 10)

<u>Distribute and break it down.</u>

24x + 48 + 40x - 20

<u>Simplify.</u>

64x + 28

<u>Perimeter For Given Value</u>

Now we'll solve for if the perimeter was 220 feet.

<u>Let's use the perimeter equation from above to find x.</u>

64x + 28 = 220

64x = 192

x = 3

<u>Now that we know x is 3, we'll substitute it into the equations in your question.</u>

12(3) + 24                        20(3) - 10

36 + 24                           60 - 10

60                                   50

The length is 60ft and the width is 50 ft.

-9x+7y=28 find the y intercept
natulia [17]

In slope-intercept form, we have these values (y = mx + b):

m = slope

b = y-intercept

Change the equation from standard form to slope-intercept form.

-9x + 7y = 28

-9x + 9x + 7y = 28 + 9x

7y = 28 + 9x

7y/7 = 28/7 + 9x/7

y = 4 + 9/7x

y = 9/7x + 4

Therefore, the y-intercept is 4.

Best of Luck!
