How do I do this? I’m not really sure.

kondaur [170]

Answer:

Step-by-step explanation:

f(x) + g(x) = 3x^2 + 2x - 1 + x^2 - 3x + 1

f(x) + g(x) = 4x^2 - x

==================================

f(x) - g(x) = 3x^2 + 2x - 1 - x^2 + 3x - 1

f(x) - g(x) = 2x^2 + 5x - 2

Find the value of x in the isosceles triangle shown below

Alex777 [14]

Answer:

x = $\sqrt{119\\}$

Step-by-step explanation:

formula for this is $\sqrt{a^{2}-(b/2)^{2}}$ where a is the altitude and b is the base

altitude = 12

base = 10

$\sqrt{12^{2}-(10/2)^{2} }$

$\sqrt{144-5^{2} }$

$\sqrt{144-25}$

$\sqrt{119}$ ≈ 10.9

so I would say x = $\sqrt{119}$ or 10.9, but seeing as thats not an option, then I'm not sure
