Area is 96 length is 4x+8 width is x find x
dimulka [17.4K]

Answer

Step-by-step explanation:

The area would be length times width. x(4x+8) =96

4x^2+8x = 96

4x^2+8x-96=0. We need to factor.

It would be factored to (4x-16)(x+6) = 0

x would be -6 (x+6=0)

or x would be 4 (4x-16=0)

Why would the width be negative?!? So the answer is 4

Wha is the nth term of 2 5 8 11 14
djyliett [7]
If you look at the sequence, you would observe:

5 - 2 = 3, 8 - 5 = 3, 11 - 8 = 3.

There is a common difference of 3, so the sequence is an Arithmetic Progression.

nth term of an AP =   a + (n - 1)d

where a = 1st term = 2, d = common difference = 3

nth term of an AP =   a + (n - 1)d

nth term of an AP =   2 + (n - 1)*3 = 2 + 3*n  - 3*1 = 2 + 3n - 3

=  2 - 3 + 3n

= -1 + 3n

= 3n - 1

The nth term =  3n - 1,  where n = 1, 2, 3, 4, 5,....

I hope this explains it.
