At another school they sell a different brand of gift wrap which costs $2 per package and cards for $5 per package. Your friends
zhenek [66]
Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55    ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards 

695/2=347 packages without cards 

SO

139 packages with card 

347 packages without card

2xsquare+12x+19<br> Find the minimum value of f (x)
Arturiano [62]
Converting to vertex form is one way of doing this
2x^2 + 12x + 19 
= 2(x^2 + 6x) + 19
= 2 [ x + 3)^2  - 9] + 19
=  2(x + 3)^2  - 18 + 19
= 2(x + 3)^2 + 1

the minimum value is 1
