Volume of a Rectangular pyramid:

V = (lwh)/3

Given:

l = 10

w = 10

h = 9

Work:

V = (lwh)/3

V = (10 * 10 * 9)/3

V = 900/3

V = 300

Answer:

$6(x - 3) = 3x + 9 \\ \\ 6x - 18 = 3x + 9 \\ \\ 6x - 3x = 18 + 9 \\ \\ 3x = 27 \\ \\ x = \frac{27}{3} \\ \\ x = 9$

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

<h3>let's solve:</h3>

$\sf cancel \: 4 \: from \: both \: sides : \\ \sf \implies \: 3x + 4 - 4 = 22 - 4 \\ \implies \sf \: 3x = 18$
$\sf divide \: both \: sides \: by \: 3 : \\ \sf \bcancel \frac{3x}{3} = \frac{ \cancel{18} \: \: ^{6} }{ \cancel{ \: 3}} \\ \therefore \rm \: x = 6$
