Answer:

x.1 = x

1 is the multiplicative identity.

Step-by-step explanation:

The product of any number, x, multiplied by 1 is x.

x.1 = x

Any number multiplied by 1, we get the same number. Because 1 is the multiplicative identity.

Let me show you a few more examples.

356 times 1 = 356

-5 times 1 = -5

22 times 1 = 22

You can see that any number multiplied by 1, we get the same number.

1 is called multiplicative identity.

It would be still be X. Any number times 1 is that number. For example 3x1=3 and 325x1=325 :)

Answer:

45

Step-by-step explanation:

You already solved that the 2 angles of the triangle are 55° and since all of the angles are on a straight line, they add up to 180°

and the equation becomes...

3x-10+55=180

3x+45=180

Subtract 45 from both sides

3x=135

Divide by 3

x= 45

Then to double check you plug 45 as the value of x in.

3(45)-10+55=180

135-10+55=180

125+55=180

180=180

SOLVE x^4 − 15x^2 − 16 = 0 <br> What are the roots of the equation?
kakasveta [241]

Answer:

roots : 4, -4, i, -i

Step-by-step explanation:

This gets a bit tricky.

We have to substitude x^2 as u in this problem.

Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get

u^2 - 15u - 16 = 0

( u - 16) (u + 1)

U = 16

U = -1

<em>This is not the end of the problem. </em>

Now we have to substitute x^2 back to u.

x^2 = 16  --> we get the roots 4 and -4

x^2 = -1 --> we get the roots i and -i

tadah!
