Answer: Discriminant.
Step-by-step explanation:
1. The quadratic formula is:

2. And the discriminant is inside the square root:

2. Then, if the discriminant is negative, the quadratic equation does not have real solutions, it has two imaginary solutions. If the discriminant is zero the quadratic has one solution. If the discriminant is positive, the quadratic equation has two distinct solutions.
Answer:
A
Step-by-step explanation:
All you have to is multiply 5x20 = 100 and 5 x 10 = 50 Then add and you get 150.
Answer:
Mary is
times heavier than her sister
Step-by-step explanation:
Mary's Weight = n
Sister's Weight = n - 15
To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.
<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:
(n - 15) * x = n
x = n/(n - 15)
Answer:
20 square units
Step-by-step explanation:
we know that
The area of rectangle is equal to

In this problem

the formula to calculate the distance between two points is equal to
<em>Find the distance WX</em>
we have
W(-3,1), X(3,3)
substitute the values in the formula
<em>Find the distance XY</em>
we have
X(3,3),Y(4,0)
substitute the values in the formula
<em>Find the area of rectangle</em>

substitute the values
