Answer:
Infinite solutions
Step-by-step explanation:
Simplify both sides, subtract 9x, and add 21x to both sides and you will get 0 = 0 so there is infinite solutions.
Answer:
32 sq. ft.
Step-by-step explanation:
1/2 (8x8)=1/2(64)=32
Answer:
The discriminant of ax^2+bx+c is b^2-4ac.
If the discriminant, d, is:
d<0, there are no real solutions (there are two imaginary solutions however)
d=0, there is one real solution
d>0, there are two real solutions
In this case d=16-32=-16 so there are two imaginary solutions. Or from your answer choices, it can be said that there are no real number solutions becuse the discriminant is less than zero.
A=pi*r^2=pi*12^2=452.39 cm^2
Answer:
82 feet
Step-by-step explanation:
