If<br>f(x)=x^2+2x-4<br>and <br>g(x)=3x+1 <br>find <br>f(g(x))=__x^2+__x+__<br>​
Korvikt [17]

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1

GEOMETRY! PLEASE SHOW YOUR WORK.
skelet666 [1.2K]

Given:

The base of the given triangle has two part:

Left( left side of the hypotenuse) = 25

Right ( right side of the hypotenuse) = x

The altitude (h) = 60

To find the value of x.

Formula:

By Altitude rule we know that, the altitude of a triangle is mean proportional between the right and left part of the hypotenuse,

\frac{left}{altitude} =\frac{altitude}{right}

Now,

Putting,

left = 25, altitude = 60 and right = x we get,

\frac{25}{60} = \frac{60}{x}

or,  (25)(x)=(60)(60) [ by cross multiplication]

or, x= \frac{3600}{25}

or, x=144

Hence,

The value of x is 144.
