Length = 6x - 12

Width = x

Area of a rectangle:

A = length x width

3744 = (x)(6x - 12)

3744 = 6x^2 - 12x

6x^2 - 12x - 3744 = 0

Use the quadratic equation to solve for x. The two solutions end up being 26 and -24. Since length is a scalar measurement, it can only be positive. Thus, the value of x is equal to 26 inches.

Width = 26 inches

Length = 6(26) - 12 = 144 inches

Hope this helps!! :)

Find volume of sphere in cubic yards whose radius is 5 yard<br><br> Use pi = 3.14​
enyata [817]

Answer:

523.333 cubic yards

Step-by-step explanation:

The formula for the volume of a sphere is  \frac{4}{3}\pi r^{3} where r is the radius.

The radius of the given sphere is r=5 yards and \pi =3.14.

Therefore, we can substitute in the radius and solve:

V_{sphere}= \frac{4}{3}\*\times3.14\times  5^{3} =523.333 cubic yards

The y-intercept of g(x) in g(x) = 3x - 2 is (0,-2) (0,0) (2/3,0)
Dennis_Churaev [7]
For any y-intercept, the x-coordinate is zero. This is something to bear in mind to start with.

Now to find the y-intercept, find g(0) = -2.

Therefore the answer is (0,-2)
