Write the following function in standard form. show your work. y=(x-5)(x+5)(2x-1)

Step-by-step explanation:

The given function is

Observe that, the first two factors are from difference of two squares.

We expand the brackets using the distributive property to obtain;

The above function is now in standard form, since the terms are arranged in descending powers of .

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
