Answer:
174
Step-by-step explanation:
L = 68
W=19
Use the formula given:
2 x 68 + 2 x 19 = 174
So it can be known anywhere. So we use all of the same measurements
Think of how many there are. im not sure if you put these into ratios or not...
like for number 3 think of how many numbers 1-9 are multiples of three
1 2 3 4 5 6 7 8 9
and once you get that number you make it out of 9 because there were 9 numbers
Example
3:9 3/9
for questions one and two its out of 52 and if you don't know how many clubs and hearts are in a deck you can look it up and put it in a ratio with 52
-3(y+2)^2-5+6y
-3(y^2+4y+4)-5+6y
-3y^2-12y-12-5+6y
-3y^2-6y-17
