Mathematics

ruslelena [56]3 years ago

Answer:

Step-by-step explanation:          

                                                                                       1

Given x³, we can write the equivalent expression -----------

                                                                                    x^(-3)

                                                              1

Given y^(-4) we can rewrite this as  ----------

                                                             y^4

Here we're applying the "rule of negative exponents."

Laurie says summer is 1 over 4 of the year. Maria says summer is 3 over 12 of the year. Who is correct? explain
nasty-shy [4]

Answer:


Step-by-ste

Oh, oh! This is such a tricky question...

Guess what!

Both of them are correct. Why?

Because if we simplify 3/12, we get 1/4th!

(How do you simplify?)

3/12 = 1/4

Because if we divide both "3" and "12" in 3/12 by 3, we get 1 instead of 3 and 4 instead of 12.


I hope you've got it! ;)

Simplify. (-2)-3 -8 - 8 user: simplify. 6x-2
Vinvika [58]
If you would like to simplify <span>(-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:

</span><span>(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21

6x - 2 = 2 * (3x - 1)

The correct result would be - 21 and </span><span>2 * (3x - 1).</span>

Sarah received a gift in a rectangular box with a volume of 240 in3. If the base of the box was 20 in2, how tall was the box?
Murrr4er [49]
V = l * w * h
240 = 20* h
divide both sides by 20
12 = h
height = 12 inches
