The answer is 16 2/3 as explained above
Answer:
(3x + 1)²
Step-by-step explanation:
Given
9x² + 6x + 1 ← is a perfect square of the form
(ax + b)² = a²x² + 2abx + b²
Compare like terms to find a and b
a²x² = 9x² ⇒ a² = 9 ⇒ a =
= 3
b² = 1 ⇒ b =
= 1
and 2ab = 2 × 3 × 1 = 6
Thus
9x² + 6x + 1 = (3x + 1)²

Answer:
The answer is 75.
Step-by-step explanation:
Average rate of change = Δy/Δx
y^2 - y^1/x^2 - x^1
925 - 400/12 - 5 = 525/7 = 75
