Letting 15 be the length, we have

2(7 x 4.5) + 2* 15 ( 7 + 4.5) =

2(31.5) + 30(11.5)  =

63 + 345 

408 sq in

My body doesn't feel "immortal"......particularly, in the mornings....!!!!!

Well, young lady....you just put those five seconds right back.....Melody and I don't have much time left, as it is !!!

We have

22000 = 5000(1 + .03/4)^(4t)   divide both sides by 5000

22/5  = (1.0075)^(4t)   take the log of both sides

log(22/5)  = log(1.0075)^(4t)   and we can write

log(4.4) = (4t)*log(1.0075)   divide both sides by log(1.0075)

log(4.4)/log(1.0075)  = 4t     divide both sides by 4

log(4.4) / [4*log(1.0075)  = t ≈ 49.6 years

In what event???

[2 + 1/6] x  [1 + 1/4 ] x [ 2 + 2/3 ] =

[13 /6 ] x [ 5/4 ] x [ 8/3] =

[13/6] x [5/3] x [ 8/4] =

[13/6] x [5/3] x 2 =

[2/6] * 13 * [5/3] =

[1/3] * [ 13] * [5/3] =

[13/3] * [ 5/3] =

65/9 =

7 + 2/9  =

7.2222

If their sum is T, then when 1 is added to each....the new sum will be T + 4

And...

3(T + 4)  =

3T + 12

247 = 19 x 13

I'm not sure what you mean......numbers only have negative logs if they lie between 0 and 1......
