Answer:

125

Step-by-step explanation:

let's see if we can find a pattern

1 = 1 = 1^2

1 + 3 = 4 = 2^2

1 + 3 + 5 = 9 = 3^2

we are starting to see a pattern here, when we add another term, we find the next integer squared.

we can find this last number in our sequence with 2x-1.

so in the next line we should find 4^2. if we plug 4 into 2x-1 we would expect the last term in the sum to be 7.

1 + 3 + 5 + 7 = 16 = 4^2

so 2*63 -1 = 126 - 1 = 125

Which of the following sets of points are vertices of a right triangle?
grandymaker [24]

  • Please find the picture for your triangle.
  • We know, area of a ∆ = <u>1/2 × base × height</u>
  • Here, base = ( 1 + 7 ) units = <u>8 units</u>
  • Height = ( 7 - 1 ) units = <u>6 units</u>
  • Therefore, area of the ∆
  • = <u>(1/2 × 8 × 6) square units</u>
  • = <u>24 square units.</u>

<u>Answer</u><u>:</u>

<em><u>2</u><u>4</u><u> </u><u>square </u></em><em><u>units</u></em>

Hope you can get an idea from it.

Carry on learning.
