Answer:

  • D. A = x² + 44x = 808

Step-by-step explanation:

Check if the relationship is linear. Verify the difference between areas.

We can see the difference is not common.

It means we can exclude options B and C.

The remaining options are quadratic (A and D).

<u>Try the last column with option A:</u>

  • 4813 = 45² + 1908
  • 4813 = 3933
  • False

<u>Verify the last option:</u>

  • 4813 = 45² + 44*45 + 808
  • 4813 = 4813
  • Correct

We can check and confirm the other columns are correct as well.

The sides of a quadrilateral are x,x+3,x+4,x+5. it’s perimeter is 52, find the lengths of the sides
wariber [46]

Answer: 10 , 13 , 14 , 15

Step-by-step explanation:

To find the perimeter of a quadrilateral , we will add all its side , that is

Perimeter = x + x + 3 + x + 4 + x + 5

That is

52 = x + x + 3 + x + 4 + x + 5

52 = 4x + 12

subtract 12 from both sides

40 = 4x

divide through by 4

x = 10

therefore , the lengths of the sides are

10 , 10+3 , 10 + 4 , 10 + 5 , that is

10 , 13 , 14 , 15
