Answer A.
1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals

(units)
Area of 1 lateral side of pyramid ABCDE is

so the total lateral area is

(units squared)
and the total surface area is

(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is

so the total area of the second pyramid is

So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is

times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is

units squared larger than the total area of the original pyramid.
Answer:
<h2>-9 ≥ (2/5x) + 7</h2>
Step-by-step explanation:
the sign must have a line underneath itself to show that it can be equal and unequal. 2/5 times a number (from my understanding) is 2/5 times a variable, plus 7.
Other guy is wrong the value of 17 does not matter in this question. 17 is the hypotenuse of the base triangles.
V = 1/2*a*c*h
V=1/2*15*15*8
V=225*4
V=900
