Find the volume of a CUBE if its side length is : x+2 in polynomial form
goldfiish [28.3K]
Volume = Length x Length x Length

Volume :

(x + 2) (x + 2) (x + 2)

= (x² + 4x + 4)(x + 2)

= x³ + 2x² + 4x² + 8x + 4x + 8

= x³ + 6x² + 12x + 8

Answer: x³ + 6x² + 12x + 8

Someone please help!!
steposvetlana [31]

Answer:

y-6 = -7x + 21

Step-by-step explanation:

Find the slope

(-8 - 6)/(5-3)

-14/2 = -7

Now find the formula

y-6=-7(x - 3)

y-6 = -7x + 21

Another way to write it is

y= -7x + 27

I got 13.7 is that correct
Ghella [55]

Answer:

The answer to your question is 10.5 in

Step-by-step explanation:

Data

First triangle

height = x

base = 7 in

Second triangle

height = 12 in

base = 8 in

Process

1.- Use proportions to solve this problem, relates the sides of a triangle with the same sides of the other triangle.

                                   \frac{x}{7} = \frac{12}{8}

2.- Multiply both sides by 7

                                7\frac{x}{7} = \frac{7(12)}{8}

3.- Simplify

                                 x = \frac{84}{8}

4.- Result

                                x = 10.5 in
