Which expression is equivalent to (2x + 4)2 – (2x2 + 6)?

Anettt [7]

Answer:

The correct option is B). $2x^{2}+16x+10$

Step-by-step explanation:

Given function is $(2x+4)^{2}-(2x^{2} +6)$

On simplifying,

= $(2x+4)^{2}-(2x^{2} +6)$

= $[4x^{2}+16x+16]-(2x^{2} +6)$

= $4x^{2}+16x+16-2x^{2}-6$

= $2x^{2}+16x+10$

Thus, The correct option is B). $2x^{2}+16x+10$

each cube inside the rectangular prism has an edge length 3/4 inch.What is the volume of the rectangular prism?

NNADVOKAT [17]

Answer:

$\frac{27}{64}n\,\,cubic\,\, inches$

Step-by-step explanation:

Given: Edge length of cube = $\frac{3}{4}\,\,inch$

To find: Volume of the rectangular prism

Solution:

A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.

A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.

Let n denotes number of cubes inside the rectangular prism

Volume of one cube = $(edge)^3=(\frac{3}{4})^3 =\frac{27}{64}$ cubic inches

So, volume of rectangular prism = volume of n cubes = $\frac{27}{64}n\,\,cubic\,\, inches$

The vertex of this parabola is at (2, -4). When the y-value is -1, the x-value is 3. What is the coefficient of the squared term

Blizzard [7]

$\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{2}{ h},\stackrel{-4}{ k})\\\\
-------------------------------\\\\
\underline{y}=a(\underline{x}-2)^2-4
\\\\\\
\textit{we also know that }
\begin{cases}
y=-1\\
x=3
\end{cases}\implies \underline{-1}=a(\underline{3}-2)^2-4
\\\\\\
3=a(1)^2\implies 3=a$
