Elena L [17]

The trinomial did she factor is \rm x^2-4x-12.

Given

Leonora is factoring a trinomial.

The factors of the trinomial are shown on the model.

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square-shaped.

1 is labeled + x squared, this gives x².

And 6 are labeled negative. 3 tiles are in the Factor 2 spot:

1 is labeled x and 2 are labeled. 0 tiles are in the Product spot.

-6x + 2x -12

Therefore

The trinomial did she factor is;

\rm x^2-4x-12

Hence, The trinomial did she factor is \rm x^2-4x-12.

More about the quadratic equation link is given below.

Find m+n <br><br> pls help !!!
podryga [215]

Answer:

  • m + n = 140

===============

<h3>Given</h3>

  • Two parallel lines,
  • Included triangle between the parallel lines,
  • Two interior angles of the triangle are m and n,
  • Another angle of 40°.

<h3>To find </h3>

  • The sum of angles m and n

<h3>Solution</h3>

As per given, the missing interior angle is corresponding with 40° angle.

Since corresponding angles are equal, the third interior angle of the triangle is 40°.

Sum of three interior angles is 180°:

  • m + n + 40 = 180
  • m + n = 180 - 40
  • m + n = 140

A right circular cone has a radius of 6 inches and a volume of 180 cubic inches. What is the height of the cone? A. 5 in. B. 15
dlinn [17]

Answer:

A. 5 in.

Step-by-step explanation:

The formula for the volume of a cone is :

V= \pi  r^{2} \frac{h}{3}

so

180 in.^{3} = \pi * 6^{2}* \frac{h}{3}

180 in.^{3} = 3.14* 36* \frac{h}{3} \\180 in.^{3} = 113.04 * \frac{h}{3}\\3 * 180 in.^{3} = 113.04 * \frac{h}{3} * 3 \\\\\\\

540 / 113.04 = 113.04 h /113.04\\h = 4.8 in

When you round you get

h= a. 5 in.
