√21*(√3+√14)=

=√(21*3)+ √(21*14)

=√(7*3²)+ √(3*7²*2)

=3√7+7√6

Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 s

Stells [14]

Answer:

Part 1) The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid

Part 2) The dimensions of this surface are 6 in x 6 in

Part 3) Molly needs to paint 228 square inches

Step-by-step explanation:

The picture of the question in the attached figure

Part 1) Which surface is shared by the two solids?

we know that

The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid

Part 2) What are the dimensions of this surface?

The surface is a square with side length 6 inches

The dimensions of this surface are 6 in x 6 in

Part 3) what is the area molly needs to paint?

we know that

The area that Molly needs to paint is equal to the surface area of the cube plus the surface area of the pyramid minus two times the area of the surface that is shared by the two solids

$SA=216+84-2(6^2)$

$SA=228\ in^2$

therefore

Molly needs to paint 228 square inches

each statement below describes the transformation of the graph f(x)=x square. which statement correctly describes the graph of g

Vitek1552 [10]

Answer:

The correct option is:

The graph of g(x) is the graph of f(x) translated 7 units up and 7 units right.

Option A is correct option.

Step-by-step explanation:

The parent function is: $f(x)=\sqrt{x}$

The transformed function is: $g(x)=\sqrt{x-7} +7$

We need to find the statement that best describes the transformed function.

We know the transformation rule:

If f(x) is transformed into f(x)+c, then the function is transformed vertically c units up.

If f(x) is transformed into f(x)-c, then the function is transformed vertically c units down.

If f(x) is transformed into f(x-c) then the function is transformed right c units.

If f(x) is transformed into f(x+c) then the function is transformed left c units.

So, In the given transformation:

The parent function is: $f(x)=x^2$

The transformed function is: $g(x)=\sqrt{x-7} +7$

The transformed function is shifted 7 units up $g(x)=\sqrt{x-7} \mathbf{ +7}$ and 7 units right $g(x)=\sqrt{x\mathbf{-7}} +7$

So, The correct option is:

The graph of g(x) is the graph of f(x) translated 7 units up and 7 units right.

Option A is correct option.

Solve for q<br> (Please show all work thank you:))

Masja [62]

Answer:

q = ± $\frac{5}{4\sqrt{p} }$

Step-by-step explanation:

We are to solve for q in:

16pq² = 25

q² = $\frac{25}{16p}$

$\sqrt{q^2}$ = ± $\sqrt{\frac{25}{16p} }$ = ± $\frac{5}{4\sqrt{p} }$
