Answer:
384
Step-by-step explanation:
Im going to separate this into 2 shapes a square and a rectangle and add them together later
so the squares dimensions are 12 by 12
so 12*12=144
next is the rectangle so its dimensions are 12*20
so 12*20=240
240+144=384
Enjoy and good luck^^

Answer:
Step-by-step explanation:
It seems to me that you are being asked for what values of x does f(x) + g(x) = 0. Which means that you need to add them together, combine like terms if possible, and then factor. Adding them together gives you
This doesn't factor to integer solutions, so we will use the quadratic formula to factor it. The quadratic formula is as follows:
For us, a = 1, b = 6, c = 4. Filling in accordingly:
and simplifying a bit:
The square root of 20 can be simplified down to 2√5, so plugging that in gives us:
and then reducing everything down to its lowest terms:
x = -3 ± √5. Those are irrational numbers but they are the numbers that make that addition o to 0.
