The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 4 times the surface area of one pr
Genrish500 [490]

Answer: The answer is (a) JD should also subtract the areas of eight hidden surfaces.


Step-by-step explanation: Given that the sculpture consists of five identical prisms and he says the surface area of the sculpture is 4 times the surface area of one prism. We are to choose which one of the given four options are correct.

Since JD is calculating the surface area of the sculpture, consisting of five prisms. So, there will be eight hidden surfaces of the five prisms which will not be in count. Hence, he must subtract the areas of those eight hidden surfaces.

Please see the attached figure for more understanding, where prism A has 1 hidden surface, B has 2 hidden surfaces, C has 2 hidden surfaces, D has 2 hidden surfaces and E has 1 hidden surface.

Thus, the correct option is (a).

Standard form is ax+by=c
most likely A
y-3=1/2x+3
y=1/2x+6
-1/2x+y=6
times -2
x-2y=-12

A is the answer
if the teacher says the answer is C, argue that that is point slope form

Twice the difference of a number and 6 is 5<br> Use the variable x for the unknown number
Norma-Jean [14]
<h2>Rewriting Words as Equations</h2>

To rewrite a word equation as a numerical equation, we can recognize certain keywords and change them into numbers or operations.

  • <em>twice</em> = multiply by 2
  • <em>difference</em> = subtract
  • <em>'a number'</em> = let this be <em>x</em>
  • <em>is</em> = equals

<h2>Solving the Question</h2>

We're given:

  • Twice the difference of a number and 6 is 5
    ⇒ twice = (2 ×)
    ⇒ difference of a number and 6 = (x - 6)
    ⇒ is 5 = ( = 5)

  • ⇒ 2(x-6) = 5

To solve for <em>x</em>, isolate the variable:

2(x-6) = 5

2x-12 = 5

2x = 17

x = \dfrac{17}{2}

<h2>Answer</h2>

\dfrac{17}{2}
