➷ The last number : n

The second number : n - 1

The third number : n - 2

n + n - 1 + n - 2

Simplify this:

3n - 3

Substitute 5 into it:

n = 5

n - 1 = (5) - 1 = 4

n - 2 = (5) - 2 = 3

3(5) - 3 = 12

Their sum is 12

Which of the following shapes have an area of 48 square feet? Select all that apply.
yKpoI14uk [10]
I think 2,3,4 or B,C,D would be correct.

The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h

1) 8(6) = 48/2 =24

2) 9(10 2/3) = 96/2 =48

3) 19.2(2.5) = 48

4) 16(3) = 48

Hope this is right and hope it helps. Have a good day
