Step-by-step explanation:
3+√5+3√5+5
=6√5+5
=6√10
For this case, the first thing we must do is define variables.
We have then:
x: initial amount of cards
We now write the equation that models the problem:


Therefore, the initial amount of cards is 300
Answer:
Latoya had 300 cards at the beginning
Answer:
slope(m)=change in y/change in x
6=y-(-1)/x-4
6=y+1/x-4
6(x-4)=y+1
6x-24=y+1
6x-24-1=y
6x-25=y
hence this is the equation
Answer: I think it is 1572 sq feet
Step-by-step explanation:

14x13x9=1638
Window is 4x4.5=18
Door 1 is8x3=24
Door 2 8x3=24
Since the doors and window are not included in what was painted you need to subtract those totals from the room.
So, 1638-18=1620
1620-48(two doors)=1572 sq feet
