Area of a circular play parachute:
A = 324 ft²
A = r² π
r² π = 324
r² = 324 : 3.14
r² = 103.1874
r = √103.1874
r = 10.157987 ≈ 10.2 ft

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

seropon [69]

Answer: Option B.

Step-by-step explanation:

Given the polynomial:

$16x^2-36x+9$

Observe that $16x^2$ and $9$ are perfect squares. Then, you can rewrite the polynomial in this form:

$(4x)^2-36x+(3)^2$

You can identify that:

$A=4\\B=3$

Then, we can check if $2AB=36$

$2(4x)(3)=36x\\\\24x\neq 36x\\\\2AB\neq36x$

Since $2AB\neq36x$ , the polynomial $16x^2-36x+9$ <em>IS NOT </em>a perfect square trinomial of the form $A^2 - 2AB + B^2$
