Factor the trinomial completely. <br> x^2-5x-24
Vikki [24]
The answer is:  " (x − 8) (x + 3) " .
__________________________________________________________
  " (x − 8) (x + 3) " are the factors of:  " x² − 5x − 24 " .
_________________________________________________________
Explanation:
__________________________________________________________

Given:  "x² − 5x − 24 " ;  Factor this "trinomial" expression completely.

We notice the "-5x" and the "-24 .

What factors of "-24" add up to "-5" ?

-1 + 24 ? No.

-24 + 1 ? no. 

-12 + 2 = -10? No.

12 + (-2) = 12 - 2 = 10 ? No.

-3 + 8 = 5 ? No.

-8 + 3 = -5 ?  Yes! 

So:   " (x − 8) (x + 3) " are the factors of:  " x² − 5x <span>− 24 " .

OFind the missingangle measures.B.m 41 =9058°A4m 42 =31089Em 3 =o
Anastaziya [24]

step 1

Find the measure of angle 1

REmember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle ABC

90+58+<1=180

148+<1=180

<1=180-148

<1=32 degrees

step 2

Find the measure of angle 2

we know that

<2=<1 -----> bt vertical angles

so

<2=32 degrees

step 3

Find the measure of angle 3

REmember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle CDE

32+108+<3=180

140+<3=180

<3=180-140

<3=40 degrees

stepan [7]

Answer:

The fuel economy is 36 miles per gallon. For each mile 1/36 gallon will be used.

Initial volume is 13,2 gallons and x is the number of miles.

<u>Our equation is:</u>

  • y = 13.2 - 1/36x

or

  • y = -1/36x + 13.2

What is the volume in cubic centimeters of a right circular cone with radius 2 centimeters and height 9 centimeters?
andreev551 [17]

Answer:

V = 37.7cm^3

Step-by-step explanation:

The formula for the volume of a cone is:

V = \frac{1}{3} \pi r^2h

Given:

- Radius = 2cm

- Height = 9cm

Let's plug these into the equation:

V = \frac{1}{3} \pi (2)^2(9)

Now solve:

V = \frac{1}{3} \pi (4)(9)\\V = \frac{1}{3}\pi 36\\V = \frac{36}{3}  \pi \\V = 12\pi \\V = 37.7cm^3

Therefore, the volume of the cone is 37.7cm^3.

<em>I hope this helps!!</em>
