Question

Please help will fan and medal!

George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30 - x) feet.

Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.

How many feet of fencing will George need for the dog run?
22 feet
68 feet
76 feet
82 feet

Answer 2

Please help someone this is the last question that I need help on, the homework's due tomorrow pleaseee

Answer 3

So we know that the area of the dog run is 240 square feet and that the length is 30 feet but the width is the length of the dog run minus x so lets set this up....

\(\Huge{240=30(30-x)}\)

Lets simplify to find out what x equals.

Answer 4

Can you plug in the information that you have?

Answer 5

id say 68

Answer 6

lol nvm @563blackghost got it!

Answer 7

I think @jjcoolja12 is right 68..?

Answer 8

You need to simplify it. Here:
Simplifying
240 = 30(30 + -1x)
240 = (30 * 30 + -1x * 30)
240 = (900 + -30x)

Solving:
240 = 900 + -30x

Move all terms containing x to the left, all other terms to the right.

Add '30x' to each side of the equation.
240 + 30x = 900 + -30x + 30x

Answer 9

Let's solve your equation step-by-step.
240=30(30−1x)
Step 1: Simplify both sides of the equation.
240=30(30−1x)
Simplify: (Hide steps)
240=(30)(30)+(30)(−1x)(Distribute)
240=900+−30x
240=−30x+900
Step 2: Flip the equation.
−30x+900=240
Step 3: Subtract 900 from both sides.
−30x+900−900=240−900
−30x=−660
Step 4: Divide both sides by -30.
−30x
−30
=
−660
−30
x=22
Answer:
x=22

Answer 10

i was wrong it was 22

Answer 12

Then you Combine like terms: -30x + 30x = 0
240 + 30x = 900 + 0
240 + 30x = 900

Add '-240' to each side of the equation.
240 + -240 + 30x = 900 + -240

Combine like terms: 240 + -240 = 0
0 + 30x = 900 + -240
30x = 900 + -240

Answer 13

So 22 or 68 lmao

Answer 14

Combine like terms: 900 + -240 = 660
30x = 660

Divide each side by '30'.
x = ?

Answer 15

?
