y = 12(2x - 1)(2x + 7)
y = 12(2x(2x + 7) - 1(2x + 7))
y =12(2x(2x) + 2x(7) - 1(2x) - 1(7))
y = 12(4x² + 14x - 2x - 7)
y = 12(4x² + 12x - 7)
y = 12(4x²) + 12(12x) - 12(7)
y = 48x² + 144x - 84
-48x² - 144x + y = -84
-1(-48x² - 144x + y) = -1(-84)
-1(-48x²) + 1(144x) - 1(y) = 84
48x² + 144x - y = 84
The green jar is 4/8 full
the purple is 4/6 full
the less full jar is 4/6 because 4/6 = 2/3 and 4/8=1/2
2/3 is bigger than 1/2
so the less full jar is the one having the green paint which has 4/8 of paint
Answer:
1 and 7/8 or 1.875
Step-by-step explanation:
Answer:
The center of this circle is at 
. The radius of this circle is 
.
Step-by-step explanation:
A circle with center 
and a radius of 
(
) could be expressed as:
.
(In other words, a point is on this circle if and only if the distance between that point and the center is equal to the radius.)
Rearrange this equation using binomial expansion to match the equation given in this question:
.
.
The equation in this question is:
.
Match up the coefficients of 
and 
in the two equations.:
- Coefficient of :
. - Coefficient of :
.
Thus, 
and 
.
The constants of the two equations should also match up:
.
Substitute in as well as and solve for :
.
(since .)
Therefore, the center of this circle is . The radius of this circle is .
