I'm not just going to give you that answer, i'm going to teach you how to do it for yourself. this is a function. what you do first is look at what the question is asking you, it's asking you to solve the function, when the value of x are as follows: -2, 1, 2. start with the easiest number, 1, and plug it in for x in each equation.
5• (1)^2 + 0
10• (1)^2 + 0
then set each equation equal to zero
5 • (1)^2 + 0 = 0
10 • (1)^2 + 0 = 0
now solve each equation. make sure the value value you get for the first equation is a negative number, because the question demands that by giving you "x<1"
complete the same steps for each other value to get the answers. hope this helps.
Answer:
~8.66cm
Step-by-step explanation:
The length of a diagonal of a rectangular of sides a and b is

in a cube, we can start by computing the diagonal of a rectangular side/wall containing A and then the diagonal of the rectangle formed by that diagonal and the edge leading to A. If the cube has sides a, b and c, we infer that the length is:

Using this reasoning, we can prove that in a n-dimensional space, the length of the longest diagonal of a hypercube of edge lengths
is

So the solution here is

Answer:
-2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
