How do u simplify this?<br> 4r-3+6s-8r-(4s-6)
nalin [4]
Hey there!:

4r -3 + 6s - 8r - (4s - 6)

*distribute parentheses :

=  - ( 4s ) - ( - 6 ) 

Apply minus  - plus rules

- ( - a )  = a  ;  - ( a ) = - a

 =  - 4s + 6


4r -3+ 6 s - 8r -4s + 6 = 

Group like terms :

=4r - 8r + 6s - 4s -3+6

Add similar elements: 4r - 8r= - 4r

-4r + 6s - 4s- 3+6

6s - 4s =  2s

-4r  + 2s  - 3 + 6


Add/Subtract the numbers :

-3 + 6  = 3

Therefore:

= 2s +3 - 4r

hope this helps!

Mary has 50 earring boxes the boxes measure 1 inch on each side. How many rectangular prisms all with a different size base coul
Sholpan [36]
Given:
50 earring boxes with a measure of 1 inch each side

volume of boxes = a³ = 1³ = 1 in³
total volume of boxes = 1 in³ * 50 boxes = 50 in³

volume of a rectangular prism = length * width * height
50 in³ = length * width * height

Let us assume that the height is 1 in.

length and width can be factored:
50 x 1
25 x 2
10 x 5

<span>I can only make 3 rectangular prisms</span>
