How would you integrate (2x-1)(6x+5)? is there a product rule for integration?

NikAS [45]

No, there is not a product rule for integration.

To integrate (2x - 1)(6x + 5), start expanding the product:

(2x - 1)(6x + 5) = 12x^2 + 10x - 6x - 5 = 12x^2 + 4x - 5.

Now, I guess you know how to integrate that:

∫ (12x^2 + 4x - 5) dx = ∫12x^2 dx + ∫4x dx + ∫ (-5) dx = 4x^3 + 2x^2 - 5x + C

A sailboat's Saul has three sides that are all the same length. Each side measures x - 10 units. The sail's perimeter is 63 unit

ruslelena [56]

Answer:

The value of 'x' is 31 unit

Step-by-step explanation:

Given:

Measure of each side = $x-10\ units$

Perimeter of sails = 63 units.

We need to find the value of x.

Solution:

Now we can see that from given data.

A sailboat's Saul has three sides.

Now assuming it to be triangle we get;

"Perimeter of triangle is equal to sum of all side."

So we can say that;

$x-10+x-10+x-10 =63\\\\3x-30=63$

Now adding both side by 30 we get;

$3x-30+30=63+30\\\\3x=93$

Now dividing both side by 3 we get;

$\frac{3x}{3}=\frac{93}{3}\\\\x=31 \ units$

Hence the value of 'x' is 31 units.
