How do you add 3 fractions of different denominators

Step 1: Find the Lowest Common Multiple between the denominators.

Step 2: Multiply the numerator and denominator of each fraction by a number (the one that will get them to the lcm) so that they have the LCM as their new denominator.

Step 3: Add or subtract the numerators and keep the denominator the same.

First, then the denominations the same! So, find a product (which is a answer to a multiplication problem) that both numbers can go in! then change the numerator also, by the same multiplication, and then u add! Remember that before u add fractions, u always need to have same denominators!

5x + 3(2x -1) = 3x -14 solve it

Umnica [9.8K]

Answer:

x=-11/8

Step-by-step explanation:

First use the Distributive property on [3(2x-1)]:

5x+6x-3=3x-14

Now combine alike terms:

11x-3=3x-14

Now add three to both sides:

11x=3x-11

Now subtract 3x from both sides:

8x=-11

Now divide both sides by 8:

x=-11/8

This fraction cannot be simplified meaning your final answer SHOULD be -11/8

Find the area bounded by the graphs of the indicated equations over the given interval.

NeX [460]

Answer:

48

Step-by-step explanation:

$y = 0$

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.

$y = {x}^{2} - 25$

We then get

$\frac{ {x}^{3} }{3} - 25x$

Evaluate at -3

$\frac{ - 3 {}^{3} }{3} - 25( - 3)$

$- 27 + 75 = 48$

Then we evaluate at 0

$\frac{0 {}^{3} }{3} - 25(0) = 0$

Next, we subtract the the answer then we get

$48 - 0 = 48$
