Two identical square pyramids were joined at their bases to form the composite figure below.

Which expression represents the total surface area, in square centimeters, of the figure?

Step-by-step explanation:

The given options are

A. 8 (one-half (24) (5))

B. 8 (one-half (24) (13))

C. (24) (24) + 8 (one-half (24) (5))

D. (24) (24) + 8 (one-half (24) (13))

We, should know that, the base area is covered and it cannot be seen, so the shape does not have a physical base area.

Then,

We need to find the area of the 8 sides triangle that formed the pyramid

Area of a triangle is ½base × height

But for a pyramid the height is the slant height

Then, the eight triangles are identical

Then, the area of the eight triangles is

A = 8 × ½ base × slant height

From the diagram,

The base length is 24cm

And the slant height is 13cm

Then,

A = 8 × ½ b × l

A = 8 × one-half × 24 × 13

A = 8(one-half)(24)(13) cm²

So, the correct answer is B

Numeral value

A = 8 × ½ × 24 × 13

A = 1248 cm²

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
