Answer:

I'd say x=2

Step-by-step explanation:

use distributive property first to get...

-2 + 12x - 9 = 16

now look for the like terms and solve...

-2 + 12x -9 = 16

+2 +2

12x -7+7 = 16 +7

12x = 24

/12 /12

x=2

-2 + 3(4x - 3) = 16
-2 + 12x - 9 = 16
-11 + 12x = 16
-11 + 11 + 12x = 16 + 11
12x = 27
12x/12 = 27/12
X = 2 3/12
X = 2 1/4

A solid oblique pyramid has a square base with edges measuring x cm. The height of the pyramid is (x + 2) cm. Which expression r
zavuch27 [327]

we know that

the volume of a solid oblique pyramid is equal to

V=\frac{1}{3}*B*h

where

B is the area of the base

h is the height of the pyramid

in this problem we have that

B is a square

B=b^{2}

where

<u>b=x\ cm</u>

so

B=x^{2}\ cm^{2}

h=(x+2)\ cm

substitute in the formula of volume

V=\frac{1}{3}*x^{2}*(x+2)\\ \\V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}

therefore

<u>the answer is</u>

V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}
