Total percent in first classroom = 25 x 86 = 2150
Total percent in second classroom = 15 x 94 = 1410
Total for both rooms = 2150 + 1410 = 3560 for 40 students
Average score across both rooms = 3560/40 = 89%

HeLp PlEasE What is the factored form of the following expression? 9x2 + 18x + 9 A. 3(x + 3)(3x + 1) B. 9(x + 1)2 C. (9x + 1)(x
AnnyKZ [126]

Answer:

<h2>The answer is option B </h2>

Step-by-step explanation:

9x² + 18x + 9

<u>Factor out 9 from the expression</u>

That's

9( x² + 2x + 1)

Using the identity

a² + 2ab + b² = ( a + b)² factor the expression

We have the final answer as

<h3>9( x + 1)²</h3>

Hope this helps you
