Answer:

$12n^2-5n-2$

The expression (3n-2)(4n+1) can be factored with the Distributive Property. It cannot be factored with a Least Common Multiple (LCM), for instance, because the terms within each set of parentheses are completely simplified.

Step-by-step explanation:

Part I

. $1. (3n-2)(4n+1)\\2. F.O.I.L.: 12n^2+3n-8n-2\\3. Simplify: 12n^2-5n-2\\$

Good luck to you!

What is BC ? Enter your answer in the box. BC= units

kumpel [21]

Answer:

The length of BC is 25 units.

Step-by-step explanation:

We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.

=> 4x + 1 = 2x + 23
=> 4x - 2x = -1 + 23
=> 2x = 22
=> x = 11

Now, let's substitute the value into the expression.

=> 3x - 8
=> 3(11) - 8
=> 33 - 8
=> 25

Hence, the length of BC is 25 units.

Hoped this helped.

The polygon is a regular nonagon (9-sides). What is the sum of the interior angles? What is the measurement for each angle?

lana66690 [7]

Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
