To solve the quadratic equation given by 0=x^2-9x-20, we use the quadratic formula given by:
x=[-b+\- sqrt(b^2-4ac)]/(2a)
where,
a=1,b=-9,c=-20
thus substituting the above values into our formula we get:
x=[9+\-sqrt(9^2-4(-20*1))/(2*1)
x=[9+\-sqrt(161)]/2
x=[9+sqrt161]/2 or x=[9-sqrt161]/2
Q: can you find the volume of the tank based on the opposite sides as the bases.
This one was a tricky one lol.
To find volume you need a formula:
Formula for volume varies on the shape of the object.
<span><span>Cube = a 3<span>a is the side length
</span></span><span>Rectangular prism = a * b * c<span>a, b, c are the length, width, and height
</span></span><span>Cylinder = π * r 2 * h<span><span>r is the radius of the circular base</span><span>h is the height
for this one you would need the Rectangular prism formula.
A: No you cannot find the volume because you need length, width, and height to figure out the volume of the rectangular prism.
Hope this helped! :)

Answer:
0
Step-by-step explanation:
Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.
In this case, the change in y was 6 - 6 which equals 0.
The change in x was -5 - 2 which was -7.
Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.
Therefore, your answer would be 0.
I hope this helped :)
Answer:
She can attend 6 Yoga classes.
Step-by-step explanation:
150 ÷ 13 is about 11.Then multiply 11x 13 and that equals 143. Then you subtract 65 from 143 and you get 78. Then 78 divided by 13 equals 6.
Its a square( same sides)
its a right-angled triangle as half
18²=a²+a²
a=12.73
