ANSWER

EXPLANATION
The given function is:

Factor -3 for the first 2 terms.

We add and subtract the square of the coefficient of x.

Factor the perfect square trinomial.

The vertex form is:

8 units
Circumference = pi * 2 * radius
50.24 = 3.14 * 2 * radius
50.24 = 6.28 * radius
8 = radius
Answer:
Step-by-step explanation:
A =
h = 10 cm , b = 17 cm
A = 10 × 17 ÷ 2 = 85 cm²
It is a trinomial because it has 3 terms.
