Question

Fanning and Giving medal for checking my answer !

Answer 1

I'll be glad to check the answer if you would tell me how you got l=30 as the \(maximum\) length.

Answer 2

@mathmate i graphed it and checked the y-intercept and saw 30 and 90 but 90 made no sense so i went with 30

Answer 3

Can you sketch the graph for me using "draw"?

Answer 4

im timed and i dont have much time @mathmate

Answer 5

thats why i just wanted to see if i was right or not

Answer 6

By the way, there are two lines to your graph, each corresponding to an equality.
The answer is the intersection of the two lines, and not the y-intercept.
Hope that helps.

Answer 7

but here's the graph

Answer 8

it did thanks

Answer 9

So what do you get for your answer?

Answer 10

ok, hope you get the correct value!

Answer 11

Your graph is correct, by the way, as long as x and y represent the right quantity.

Answer 12

if you were to use substitution
2l + 2(0.5l) = 180
3l = 180
l= 60
where l = length
