Answer:

20 feet

Step-by-step explanation:

Remember the Pythagorean theorem,

x^2 + y^2 = n^2

in this case

x= 16

y = 12

so substitute back into the equation

16^2 + 12^2 = n^2

256 + 144 = n^2

400 = n^2

sqrt ( 400) = n

20 = n

LuckyWell [14K]

Answer:

3(-x^2-6x+4)

Step-by-step explanation:

3 (-3x^2 over 3 - 2x3^2 times x over 3 + 262 x 3 over 3)

3(-(x^2) - (2 x 3^2-1 times x) +2^2

3(-x^2 - (2 times 3x) +4)

3(-x^2-(6x) + 4)

3(-x^2 - 6x + 4)
