Let d=discriminant. The the rule is:
d>0, there are two real solutions
d=0, there is one real solution
d<0, there is no real solutions (but there are two imaginary solutions)
So if it is positive, there are two real solutions.
Answer:
2(3.14(4)^2)
100.48
answer: 100.5
Step-by-step explanation:
Answer:
<u>Length</u> - 54 yds
<u>Width</u> - 18 yds
Step-by-step explanation:
72 yds = perimeter
3x + x =72
4x = 72
Since 4x equals 72, you would divide 72 by 4 to find out how much x equals.
72/4 = 18 yds
18 yds = width
Since the length is three times as long as the width, you would multiply 18 by 3.
18 x 3 = 54
54 yds = length
