Answer:

x = 144

Step-by-step explanation:

Angle sum of heptagon = 900

5x + 90 + 90 = 900
5x + 180 = 900
5x + 180 - 180= 900 - 180
5x = 720
Divide both sides by 5
x = 144

F(x) = 2x^2-7x-7<br> g(x) = x+1<br><br> Find f(g(x))

adell [148]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(x) = 2 {x}^{2} - 7x - 7$

$g(x) = x + 1$

_________________________________

$f(g(x)) = 2 ({x + 1})^{2} - 7(x + 1) - 7 \\$

$f(g(x)) = 2( {x}^{2} + 2x + 1) - 7x - 7 - 7 \\$

$f(g(x)) = 2 {x}^{2} + 4x + 2 - 7x - 7 - 7 \\$

Collect like terms

$f(g(x)) = 2 {x}^{2} + (4 - 7)x - 14 + 2 \\$

$f(g(x)) = 2 {x}^{2} - 3x - 12$
