Find the product.<br><br> (r + s)2

mario62 [17]

When you've got a squares bracket, this simply becomes the bracket twice, therefore, (r+s)2 becomes (r+s)(r+s)
You've then go to use FOIL, and this gives you r^2+rs+sr+s^2, and this cannot be simplified any further.
Therefore, the product of this is r^2 + s^2 + rs + sr
Hope this is what you're looking for :)

Which expression represents the volume, in cubic units, of the composite figure? One-third(8)(6)(6) (8)(6)(4) One-third(8)(6)(10

vaieri [72.5K]

The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

The correct option is (1)

<h3>What is Volume?</h3>

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

Volume of rectangular pyramid= $\frac{1}{3}$ * base area* height

= $\frac{1}{3}$ * 6*8*(10-4)

= $\frac{1}{3}$ * 6*8*6

Volume of cuboid= l*b*h

= 4*6*8

So, Volume = $\frac{1}{3}$ * 6*8*6 + 4*6*8

= $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

So, The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4).

SOMEONE SMART 15 POINTS <br> simplifying radical expressions (subtraction)

coldgirl [10]

When the radical terms are the same, just focus on the numbers that are in front of them so it's really just 6 - 9 and you get -3 (third root of 2b)
