okay so you would do it like this

2x + (3 - x)

2x + 3 - x

x + 3

the answer would be x + 3

hope this helps!

Following PEMDAS, the parentheses comes first. Essentially, (3 - x) is times 1, which removes the parentheses. So 2x + 3 - x. Subtract the x first. This leaves x + 3.

How do you find the legs of a right triangle when only given the hypotenuse?

tangare [24]

Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

$4 \sqrt{2} = \sqrt{32 } \\ \sqrt{32} ^{2} = 32$

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be 4 for both x and y
