First solve for g(1)
Plug in 1 for the equation g(x)
g(1) = -(1) + 4
g(1) = 3
Now plug 3 in for f(x)
f(3) = 3(3)^2 + 4(3) + 1
f(3) = 3(9) + 12 + 1
f(3) = 27 + 12 + 1
f(3) = 40
Solution: f(g(1)) = 40
Seventy + seventy = one hundred forty
Using the principle of parallel lines, the value of x in the given triangle is calculated to be 8
<u>The</u><u> </u><u>smaller</u><u> </u><u>triangle</u><u> </u><u>can be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base = 6/x ----(1)
<u>The</u><u> </u><u>larger</u><u> </u><u>triangle</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base
- Side = 6+9 = 15
- 15/20 - - - - - (2)
<u>Equating</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>2</u><u>)</u><u> </u><u>:</u>
6/x = 15 / 20
15x = 20 × 6
15x = 120
x = 120 / 15
x = 8
Therefore, the value of x in the triangle is 8.
