Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:

We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:

General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get


Now substituting D in
we get




Therefore, 
Answer:
True
Step-by-step explanation:
The U.S. customary system uses the fluid ounce (fl oz).
Area of a rectangle=length x width
You have two rectangles:
First rectangle (the biggest):
length=9 yd
width=12 yd-6 yd=6 yd
Area of the biggest rectangle=(9 yd)(6 yd)=54 yd²
Second rectangle (the smallest)
length=6 yd
width=3 yd
Area of the smallest rectangle=(6 yd)(3 yd)=18 yd²
Area of the ballroom=area of the biggest rectangle + area of the smallest rectangle.
area of the ballroom=54 yd² +18 yd²=72 yd²
