If triangle opq is dilated from point q by a scale factor of 3, which of the following equations is true about line r’s’
1- r’s’ = 1/2 rs
2- r’s’ = 2rs
3- r’s’ =rs
4- r’s’ = 3rs

step-by-step explanation:

idk

idk

i know the way

and

idk

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

25/6 hope it : )
