Answer:
f(-4) = -120
Step-by-step explanation:
So we know that f(x) = 11x - 5x² + 4, and we are trying to solve for f(-4). To solve for f(-4), we plug -4 for x in the equation of f(x). In other words, change all x's into -4 in the equation 11x - 5x² + 4 and then solve.
f(x) = 11x - 5x² + 4
Plug in -4 for x.
f(-4) = 11(-4) - 5(-4)² +4
Simplify. 11(-4) = -44, 5(-4)² = 5(16) = 80.
f(-4) = -44 - 80 + 4
Solve.
f(-4) = -120
The answer is f(-4) = -120.

Answer:
approximately 13.9 inches
Step-by-step explanation:
That's 8√6, not 8V7.
The four sides are of the same length (x). According to the Pythagorean Theorem, x² + x² = (diagonal length)² = (8√6)², or
2x² = 64(6) = 384
Dividing both sides by 2, we get:
x² = 192, or x² = 4(48). Then the side length is x = √16√12, or
x = 4√4√3 = 8√3. This is approximately 13.9 inches.
