Answer:

h(x) = -3 (x + 1)² + 8

Step-by-step explanation:

h(x) = -3x² − 6x + 5

Factor the leading coefficient from the first two terms.

h(x) = -3 (x² + 2x) + 5

Complete the square.

h(x) = -3 (x² + 2x + 1 − 1) + 5

h(x) = -3 (x² + 2x + 1) + 3 + 5

h(x) = -3 (x + 1)² + 8

katrin [286]

Answer:

Circumference: 37.68

Area: 113.04

Step-by-step explanation:

the formula to find the circumference is 2 x 3.14 x r

r is the radius so you plug in 6 for that

2 x 3.14 x 6 = 37.68

the formula to find the area of a circle is 3.14 x r ²

r is still the radius so you plug in 6 for that

3.14 x 6² = 113.04
