Answer:
It means that the roots of the quadratic equation are real and distinct
Step-by-step explanation:
Here, given the discriminant of the quadratic equation, we want to find out the nature of the solutions.
Mathematically, we can use to determine the nature of the discriminant.
By it’s formula;
D = b^2 - 4ac
We can see that the given discriminant 40 is a positive value. What this means is that the quadratic equation has roots which are real and are distinct
Answer:
The top of the rectangle is 12 inches in area and 14 inches in perimeter. The sides are 28 inches in area and 22 inches in perimeter.
Step-by-step explanation:
7x4=28 -area
7+7=14, 4+4=8, 14+8=22 -perimeter
3x4=12 -area
3+3=6, 4+4=8, 6+8=14 -perimeter
Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13
