Simplify this? i have no clue how to do these problems.

Basically, the question is (x^2 / x - 1) / (3x^2 / x + 4).

simplify parentheses first.  x^2 divided by x = x thus...

(x / -1) / (3x / 4)

now the x cancels out...

(-1) / (3/4)

= (-1) / (0.75)

= -1.334

I am pretty sure this is how to do it, but I think it would be wise to double check with someone.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
