Answer:

length=1.05m

perimeter=2.7m

Step-by-step explanation:

18900 in m^2=1.89 m^2

area=length*width

1.89=length*1.8 m

length=1.89÷1.8

length=1.05 m

perimeter=(l+w) 2

perimeter=(1.05+1.8)2

perimeter=2.85×2

perimeter=2.7 m

Use the discriminant to determine the number of real solutions to the quadratic equation. n^2 − n − 6 = 0 What is the number of

Andreas93 [3]

Answer: last option

Step-by-step explanation:

The formula to find the Discriminant is:

$D=b^2-4ac$

Given the quadratic equation $n^2-n-6=0$ , you can identify that:

$a=1\\b=-1\\c=-6$

Now, you can substitute values into the formula $D=b^2-4ac$ , then:

$D=b^2-4ac\\D=(1)^2-4(1)(-6)\\D=25$

As the Discriminant is greater than 0 ( $D>0$ ), then the quadratic equation $n^2-n-6=0$ has two distinct real solutions.
