<h3>36x^2 - 36xy + 9y^2 is the standard form</h3>

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

(6x-3y)^2

We have to write in standard form

Standard form means we have to write the terms by descending degree

Expand the given expression

(6x-3y)^2 = (6x-3y)(6x-3y)\\\\Simplify\\\\\rightarrow 36x^2 -18xy -18y +9y^2\\\\\rightarrow 36x^2 -36xy + 9y^2

Thus the expression is written in standard form

Two similar pyramids A and B have surface areas of 135cm^2 and 60cm^2 respectively . The volume of pyramid A is 405 cm^3 work ou
Aleks04 [339]

Answer:

120 cm^3

Step-by-step explanation:

The surface areas are in the ratio 60 to 135  so the single dimensions are in the ratio √60 to √135.

Therefore the volumes are in the ratio (√60)^3 to  (√135)^3  or 60^3/2 to  135^3/2.

So  Volume of  Pyramid B / Volume of Pyramid A

= 60^3/2 / 135^3/2.

Therefore we have the equation  60^3/2 / 135^3/2 =  V / 405  where V is the volume of pyramid B.

V = (60^3/2 * 405) / 135^3/2

=  120  cm^3
