Answer:

Step-by-step explanation:
[NOTE]
I am assuming x2 is
, if I am wrong about that then please notify me in the comments
[END NOTE]
The parenthesis are implications that we multiply the numbers within them.
Therefore, multiply.
(2x)(x2)

(2x)(x)


(2x)(-2)
-4x

(3)(x2)


(3)(x)
3x

(3)(-2)
-6

Now combine like terms, meaning the numbers with the same endings, you cannot add a number with different exponents and adding numbers with and without a variable.

Answer:
5^2 + h^2 = 10^2
Step-by-step explanation:
This is a clear example of the Pythagorean Theorem, a relation of all sides in a right triangle. The equation itself is a^2 + b^2 = c^2. By simply plugging in the given values into the triangle, you would get the answer.
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:

Substitute:

If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:

We have the equation:
<em>cross multiply</em>

<em>add 2 to both sides</em>

<h3>Answer: x = -4.</h3>
Answer:
-3=5
6=14
so it would be 6
Step-by-step explanation:
Since 5 + 9 is 14 you can use ANY expression that has the same final value/ sum
