Given that s^3 on the bottom 1 (e^x)dx=(e^3)-e use the properties of integrals and this result to evaluate s^3 on the bottom 1 (5e^x − 1) dx. i got 5e^3x-5e-1 is this correct? !

Remember that
1) For functions and ,
2) For a function and a constant ,

Using these two properties of integrals, and the fact that , we can see that

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

The first answer is correct
