7x - 20 = 2x - 3(3x + 2)
kirill [66]

Answer:

7x-20=2x-3(3x+2)

We move all terms to the left:

7x-20-(2x-3(3x+2))=0

We calculate terms in parentheses: -(2x-3(3x+2)), so:

2x-3(3x+2)

We multiply parentheses

2x-9x-6

We add all the numbers together, and all the variables

-7x-6

Back to the equation:

-(-7x-6)

We get rid of parentheses

7x+7x+6-20=0

We add all the numbers together, and all the variables

14x-14=0

We move all terms containing x to the left, all other terms to the right

14x=14

x=14/14

x=1

Find the volume for the regular pyramid.<br><br><br><br> V =
mylen [45]
The volume is given by:
 V = L * Apb * h
 Where,
 L: side of the base
 Apb: apothema of the base
 h: height
 Substituting we have:
 V = (4) * ((root (3) / 2) * 4) * (6)
 Rewriting we have:
 V = (4) * ((root (3) / 2) * 4) * (6)
 V = 96 * (root (3) / 2)
 V = 48 * root (3)
 Answer:
 
V = 48 * root (3)
