First you set and equation for length which is three times width
l=3w
The substitute in the perimeter, p, into the equation for perimeter which is p=2l+2w
88=2l+2w
Then substitute in length, l, with the equation previously created: l=3w
88=2(3w)+2w
Multiply 2 and 3w
88=6w+2w
Combine like terms: 6w+2w
88=8w
Divide to get the value for w
w=11
Since you figure the value for w, 11, you can plug it into the equation for length which is l=3w
l=3(11)
When you do you get
l=33
So the length is 33 and the width is 11

Answer:
0 real roots or 2 complex roots
Step-by-step explanation:
Discriminant: b² - 4ac
If d > 0, then there are 2 real zeros
If d = 0, then there is 1 real zero
If d < 0, then there are 0 real zeros and 2 complex/imaginary zeros
Simply substitute <em>a </em>= 1, <em>b</em> = -5, and <em>c</em> = 40
Our d should equal -135, showing us we have 0 real roots and 2 complex ones.
