Answer:

The 3 possible values of x are;

6, 4 and 2

Step-by-step explanation:

If the triangle is isosceles, then two of the sides must be equal

So we equate the sides, 2 at a time to get the different values of x

3x + 4 = 2x + 10

3x-2x = 10-4

x = 6

3x + 4 = x + 12

3x-x = 12-4

2x = 8

x = 8/2 = 4

2x + 10 = x + 12

2x - x = 12-10

x = 2

Given the following functions f(x) and g(x), solve f[g(10)] and select the correct answer below: f(x) = 10x + 8 g(x) = x + 9 2,0

ikadub [295]

ANSWER
$f(g(10)) = 198$

EXPLANATION

The given functions are;

$f(x) = 10x + 8$
and

$g(x) = x + 9$

To find
$f(g(10))$
we need to find

$f(g(x)) = f(x + 9)$

$f(g(x)) =10(x + 9) + 8$

$f(g(x)) =10x + 90 + 8$

$f(g(x)) =10x + 98$

$f(g(10)) = 10(10) + 98$

$f(g(10)) = 100 + 98$

$f(g(10)) = 198$

The last option is the correct answer
