Answer:
Length of Shortest Side = 12 inches
Step-by-step explanation:
Length of Shortest Side = L = 3x
Length of Longest Side = W = 5x-4
<u><em>Condition:</em></u>
2L+2W = Perimeter
2(3x)+2(5x-4) = 56
6x+10x-8 = 56
16x-8 = 56
Adding 8 to both sides
16x = 56+8
16x = 64
Dividing both sides by 14
=> x = 4
Now,
Length of the Shortest Side = L = 3(4) = 12 inches
Length of the Longest Side = W = 5(4)-4 = 16 inches
we have to find equation similar to
Firstly , we can divide both sides by 2
now, we can multiply both sides by 3
we get

Answer: I know you probably got the answer, but for anyone else who needs it, it's -1.78 and 1.78. I just took the quiz, so. :u
Step-by-step explanation:
Answer:
Quadratic, Linear, Exponential.
Step-by-step explanation:
You can find the average difference between rows. For example, in the first one, between the ys, it changes by 1, then 3, then 5, then 7. If you look at the changes between these you get 2 each time. Because you had to look at the differences twice, its quadratic. It's linear if you had to look at it once. Exponential you can just see if you can multiply the same constant between each row.
The answer for question 4:
a) 3(3n-1)=9n-3
b) 9n-3=96
9n=96+3
9n=99
n=11
