Fabiana is going to construct a rectangular metal box with a volume of 150 in.. Her box will have a length of 2 inches, a width

of 3 inches less than its length, and a height that is 1 inch more than its
length
Which cubic equation would help Fabiana find the length of the box?
O-22
3r - 1500
OZ- 2r? - 3x = 0
O 23 - 22 - 3.7 + 150 = 0
Or+? - 123=0

Enter the correct answer in the box. Solve the quadratic equation by completing the square.
viktelen [127]

Answer:

Interpreting as: X=a-sqrt b X=a+sqrt b

Input:

X = a - sqrt(b) X = a + sqrt(b)

Alternate forms:

{a = (sqrt(b) + 1) X, a = X - sqrt(b), b = 0 ∨ X = -1}

{a = (sqrt(b) + 1) X, a + sqrt(b) = X, sqrt(b) (X + 1) = 0}

A sphere has a volume of Vequals=3600 in cubedin3. Find its surface area.
Mice21 [21]
\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad 
\begin{cases}
r=radius\\
------\\
V=3600
\end{cases}\implies 3600=\cfrac{4}{3}\pi r^3
\\\\\\
3600=\cfrac{4\pi r^3}{3}\implies \sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}=\boxed{r}\\\\
-----------------------------\\\\
\textit{surface area of a sphere}\\\\
S=4\pi r^2\implies S=4\pi \left(\boxed{\sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}}  \right)^2

simplify away
