Check the picture below.
notice, the dashed line is the "continuation" of the graph, however, for the constraints in the piece-wise, is excluded.
Length = w+5
A = l x w
84 = w +5 x w
84 = w² + 5w
w = -12 or w = 7
Since you can't have a negative length W=7
Length = 7+5
length = 12
Width= 7
Answer:
x=0
Step-by-step explanation:
Since no value can be given to fit the inequality, it would be zero
1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..
I'll do the others in a different answer!!
