When you buy a coffee table or piece of circular furniture
Answer:
(-6, 0).
Step-by-step explanation:
x^2 + 36y^2 + 12x = 0
Convert to standard form:
(x + 6)^2 - 36 +36y^2 = 0
(x + 6)^2 + 36y^2 = 36
Divide through by 36:
(x + 6)^2 / 36 + (y - 0)^2/ 36 = 1
Now compare this with the general form:
(x - h)^2/a^2 + (y - k)^2/ b^2 = 1
We see that the center (h, k) = (-6, 0).
Answer:15-20 ft

Answer:
width=5inches
Step-by-step explanation:
Let the width =x
Then the length=x+3
Area of a rectangle=L×W, where Area=40inch²
Therefore we substitute the values of the dimensions into the formula
40=(x+3)(x)
40=x²+3x(grouping the terms together)
x²+3x-40=0(factorise the quadratic)
(x+8)(x-5)=0(find the zeros)
x+8=0,x=-8
x-5=0,x=5
Since the dimension, whether length or width cannot be negative,then x is 5inches hence width is 5 and length is 5+3=8inches
Answer:
432 km^3
Step-by-step explanation:
The equation to solve this would be: volume = length * width * height
v = l * w * h
v = 6 * 6 * 12
v = 432 km^3
