Change the subject of a formula to S

densk [106]

You want to "solve" this formula for s.

7s+4
If t = ----------- , then 2t = 7s + 4. Subtract 4 from both sides. Then
2
2t - 4
7s = 2t - 4, and s = -------------- (answer)

F(x)= x^3-4x^2+9 and let g(x)=6x^3+x^2-5x-12 what is f(x)-g(x)

Anarel [89]

$f(x) - g(x) = -5x^3-5x^2+5x +21$

Step-by-step explanation:

Given functions are:

$f(x) = x^3-4x^2+9\\g(x) = 6x^3+x^2-5x-12$

We have to find the difference of functions

So,

$f(x) - g(x) = x^3-4x^2+9 - (6x^3+x^2-5x-12)\\= x^3-4x^2+9-6x^3-x^2+5x+12$

Combining like terms

$x^3-4x^2+9-6x^3-x^2+5x+12\\=x^3-6x^3-4x^2-x^2+5x+9+12\\= -5x^3-5x^2+5x +21$

Hence,

$f(x) - g(x) = -5x^3-5x^2+5x +21$

The formula a=6s^2 will calculate the surface area of a cube. suppose you have a cube that has a surface area of 216 square inch

lawyer [7]

216 = 6s^2

can be solved in the following manner.

216/6=s^2
36 = s^2
sqrt(36) = s

flip for better overview

s = 6

the length of each side is 6 inches. :)
