Hi!

No they are not because x^2 has 2 as the exponent and x has 1 as the exponent. you can add them together

Hope this helps!

X^2 and X are not like terms. They have different degrees.

For example, 2x^2 and x^2 are like terms because they have the same degrees. When you add them you get 3x^2. If you try to add x^2 and x, you cant do it because they have different degrees.

Use the Pythagorean Theorem to find the length of the leg in the triangle shown below.
Natali [406]
The answer to what the length of the leg would be is 15.

You would do this problem by first writing down your Pythagorean Theorem, which is a^2 + b^2 = c^2.

Since we have our hypotenuse which is c^2 in our equation, we would write or insert the number we have.

So our equation could be that a or b leg equals 20, it doesn’t matter which one.

So we could write, 20^2 + b^2 = 25^2. So we don’t know what b leg is.

First we should figure out what 20^2 is and what 25^2 is.

20^2 is 400 and 25^2 is 625.

Our equation now comes to 400 + b^2 = 625.

Now we take 400 and subtract it from
625 -> 400 + b^2 = 625
-400.

So 625 - 400 comes out to be 225.

Lastly instead of squaring or putting 225 to the second power, we do the opposite.

So instead of squaring 225 we must square root 225. √ 225 .

The square root of √ 225 comes out to be 15.

one number is equal to two times a second number. two times the first number plus two times the second number is 24. if you let
ziro4ka [17]
X = 2y
2x + 2y = 24
So if x = 2y that means 2x = 4y. Which means that 2x + 2y = 24 can be written as 4y + 2y = 24. Simplified to 6y = 24. Now we need to get 1y so we divide both sides by 6, 6y/6 = y and 24/6 = 4. so y = 4. so x= 2y can be written as x = 8.

Finf the diffrence write your answer in simplest form 2/7+2/5
Fed [463]
The difference (the answer of a subtraction problem) is:
2/7 - 2/5  -->  10/35 - 14/35 = -4/35

The answer sum (the answer of an addition problem) is:
2/7 + 2/5  -->  10/35 + 14/35 = 24/35

Hope this helps.
