If f(x) = x2, and g(x) = x – 1, then f(g(x)) = [? ]x2+[?]+ [?]

Basile [38]

Answer:

f(g(x)) = x² - 2x + 1

The perimeter of a rectangle is equal to 10. If the length is halved and the width is doubled, the new perimeter is increased by

monitta

Step-by-step explanation:

Let's call x the lenght and y the height. The perimeter will be:

p = 2x + 2y = 10

When the lenght is halved and the height double we'll have:

p = x + 4y = 14

These 2 equations form a system of equations2 that can be solved and give as result:

y = 3

x = 2

The equation for this is: $3(n+10) = 42$

Step-by-step explanation:

We have that the number though is n.

Adds 10:

This means that now we have: $n + 10$

Multiplies by 3:

This means that now we have: $3(n+10)$

Gets 42:

This means that: $3(n+10) = 42$
