The expression that represents the surface area of the square based pyramid is 36 + 15 + 15 + 15 + 15

<h3 />

<h3>How to find the surface area of a square based pyramid?</h3>

The surface area of the pyramid is the sum of the area of the whole faces of the pyramid.

Therefore, the pyramid has 4 triangular faces and 1 square faces.

Therefore,

surface area of the pyramid = area of the square + 4(area of the triangle)

area of the square = 6² = 36

area of each triangular faces = 1 / 2 bh

where

  • b = base area
  • h = height

Therefore,

area of each triangular faces = 1 / 2 × 6 × 5 = 30 / 2  = 15

Hence, the expression is as follows:

surface area of the pyramid = 36 + 15 + 15 + 15 + 15

Use the expression for the slope from part B to write a general equation for the slope of any two points (a, b) and (c, d).
Dmitrij [34]

Using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).

<em><u>Recall:</u></em>

  • Given the slope (m) of a line, we can write an equation in point-slope form of the line can be written if we know one of the points as, y - y_1 = m(x - x_1), where (x_1, y_1) is a point on the line and m = slope.

From the question given, the slope gotten from part B is missing in this question. However, let's assume the slope (m) = 3.

Using one of the points, say (a, b), to write a general equation in point slope form, substitute (x_1, y_1) = (a, b) and m = 3 into y - y_1 = m(x - x_1).

Thus:

\mathbf{y - b = 3(x - a)}

Therefore, using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).
