Answer:
It's the first one. (m + n - 1) sqrt p
Step-by-step explanation:
We can combine m sqrt p and n sqrt p, resulting in m + n, and combine - sqrt p to become (m + n - 1)sqrt p
First, it depends how you want to solve the system. The easiest way is to solve by elimination. Eliminate the 2 s. Therefore, 4x = 8. Divide by 4 to find x. After dividing by 4, x=2. To find the y plug in 2 for x in the original equation. Try for the first one. 2 +2y =3. Subtract 2 from both sides of the equation. Then you get 2y =1. Divide by 2 in both sides and you get y = 1/2.
Answer:
= 9
Step-by-step explanation:
We need to find
which will make an equivalent fraction statement.

5 x 6 = 30
x 6 = 54 (to find
we should do 54 ÷ 6 which = 9)
So:

= 9

Well... Basically, you should prove this by SSS property(side-side-side). It's fair to say that the length of a side is equal to itself so The line that cuts through the rectangle is a side for both rectangles. Thus because of the given, all the sides of the triangles are equal to one another. This is a very important trick for geometry(I remember using it a lot).
Hope this helps!
A is your answer! Because of how many sides it has.
