harina [27]

Answer:

  • x = 5, y = 7, z = 12

Step-by-step explanation:

<u>Let the numbers be x, y and z</u>

  • x + y + z = 24
  • 2y = z + 2
  • z = x + y

<u>Solving by substitution:</u>

  • x + y + z = z + z = 24
  • 2z = 24
  • z = 12

  • 2y = z + 2
  • 2y = 12 + 2
  • 2y = 14
  • y = 7

  • z = x + y
  • x = z - y
  • x = 12 - 7 = 5

<u>The answer:</u>

  • x = 5, y = 7, z = 12

  • Determine the surface area of the right square pyramid.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

The formula for finding the surface area of a right square pyramid is ⇨ b² + 2bl, where

  • b = base of the right square pyramid
  • l = slant height of the right square pyramid.

In the given figure,

  • base (b) = 4 ft.
  • slant height (l) = 8 ft.

Now, let's substitute the values of b & l in the formula & solve it :-

\sf \: {b}^{2}  + 2bl \\  =   \sf \: {4}^{2}  + 2 \times 4 \times 8 \\  =  \sf \: 16 + 8 \times 8 \\  =  \sf \: 16 + 64 \\  =  \huge\boxed{\boxed{ \bf 80 \: ft ^{2} }}

So, the surface area of the right square pyramid is <u>8</u><u>0</u><u> </u><u>ft²</u><u>.</u>
