Answer:A

Step-by-step explanation:

from Pythagoras principle we get:

Hypotenuse=√(4^2+2^2)

Hypotenuse=√(4x4+2x2)

Hypotenuse=√(16+4)

Hypotenuse=√(20)

Hypotenuse=√(4x5)

Hypotenuse=√4 x √5

Hypotenuse=2 x √5

Hypotenuse=2√5

Perimeter=4 x hypotenuse

Perimeter=4 x 2√5

Perimeter=8√5

Given the function f(x) = −5x2 − x + 20, find f(3).

lana66690 [7]

f(x) = -5x^2 - x + 20;

f(3) = -5*3^2 - 3 + 20 = -5*9 - 3 + 20 = -45 - 3 + 20 = -28;
