Answer:

28 ft squared

Step-by-step explanation:

The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.

Answer:

900<x<1100

Step-by-step explanation:

The third side must be greater than the difference of the other two sides

10000- 1000 < 10x

9000< 10x

Divide by 10

9000/10 < x

900 < x

The third side must be smaller than the sum of the other two sides

10000+1000 > 10x

11000>10x

Divide by 10

11000/10>10x/10

1100>x

900<x<1100

4(k+1)=k+10,then 3k=<br><br>A. 3/2<br>B.5/2<br>C. 2<br>D. 6​
nasty-shy [4]

Solution:

<u>Note that:</u>

  • Given equation: 4(k + 1) = k + 10
  • To find: 3k

<u>Simplifying the LHS:</u>

  • 4(k + 1) = k + 10
  • => (4 x k) + (4 x 1) = k + 10
  • => 4k + 4 = k + 10

<u>Subtracting k and 4 both sides:</u>

  • 4k + 4 - k - 4 = k + 10 - k - 4
  • => 3k = 6 (No further solution required)

The value of 3k is 6.
