What is this just tell me what the L AND W ='s please
andreyandreev [35.5K]
You didn't show us much of the page with the question on it,
so we can't be sure of exactly what you're working on in math.

If you're working with things like squares and rectangles, then
'L' and 'W' are often used to represent the Length and Width of
shapes drawn on paper, or even Length and Width of 3D objects
like blocks or boxes.

H(x) = x2<br> j(x) = 2x2-5<br> find h(x) - j(x)
yKpoI14uk [10]

Answer:

Step-by-step explanation:

h(x) - j(x) => x^2-(2x^2-5)

The negative sign out in front of the set of parenthesis changes the signs of everything inside the parenthesis, so now we have, without parenthesis:

x^2-2x^2+5 which simplifies down to

-x^2+5
