36 \int\limits^1_0 { \frac{1}{(2 x + 1) ^{3} } } \, dx =
u = 2 x + 1,  d u = 2 d x,  d x = d u / 2
36*1/2 \int\limits^1_0 {u ^{-3} } \, du = 18 * t ^{-2}/(-2) = \\ - 9 * t^{-2}= \\ -9 * ( 2 x + 1 ) ^{-2}
- 9 / ( 2 + 1 )² - ( - 9 / ( 0 + 1 )² = 
- 9 / 9 + 9 = - 1 + 9 = 8

Answer:

10x+2

Step-by-step explanation:

First we work on the paranthesis. We will times 5 and 2x to get 10x

and then we times 5 and 3/4 to get 3\frac{3}{4}

So now we have 10x+3\frac{3}{4}-1.75

Next, we subtract 3\frac{3}{4}-1.75 which is 2

Lastly we look at the equation as a whole!

timurjin [86]
<h2><u>Full Question:</u></h2>

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

<h2><u>Answer:</u></h2>

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

<h3><u>Step-by-step explanation:</u></h3>

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.
