48 + 54 = 102

102 / (8+9) = 6

48 + 54 = 6 x (8+9)

6 can be written on the blank line to make the expressions equivalent.

How would you "remove the discontinuity" of f ? In other words, how would you define

balu736 [363]

There is a hole at x=4 because the top factors to (x-4)(x+3)
in the end we get

f(x)=(x-4)(x+3)/(x-4)
the (x-4) cancels out and we get
f(x)=x+3
so baiscally f(x) is y=x+3 but with a hole at (4,7)

one way is to make a piecewise function defined as(x^2-x-12)/(x-4) for all x≠4 and defined as 7 for x=4

or, to just do f(x)=x+3

what is the formula for calculating the length of the space diagonal of a right rectangular prism on the basis of the prism's le

Lady bird [3.3K]

The diagonal of a right rectangular prism is the line that connect opposite vertices. In other word is the distance from corner to corner in the right rectangular prism. Since the diagonal of a right rectangular prism is the hypotenuse of a right triangle, we are going to use a variation of the Pythagorean theorem to find it. In essence, we just need to add another dimension to the Pythagorean theorem; in this case the height of our prism:

We can conclude that the formula to calculate the length of the diagonal of a right rectangular prism is: $d= \sqrt{l^2+w^2+h^2}$
where
$d$ is the length of the diagonal.
$l$ is the length of the rectangular base of the prism.
$w$ is the width of the rectangular base of the prism.
$h$ is the height of the prism.
