The first step is to find the relationship between the square base and the surface area.
Surface area (SA) = area of the square (SS) + area of triangles.4(AT)
Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)
4(AT) = 864 - 324 = 540
Each triangle = 540/4 = 135 square in.
An area of one triangle (AT)= (base* slant height)/2
The base = 18 in.
<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>

Step-by-step explanation:
Answer:
42 suitcases screened = x
Step-by-step explanation:
7/24 = x/144
7(144) = 24x
1,008 = 24x
42 = x
ANSWER
The solution to the system is
EXPLANATION
The system of equations are:
and
We put equation (2) in to equation (1) to get,
We expand the parenthesis to obtain,
We group like terms to obtain,
This implies that,
We divide through by 5 to get
We substitute the value of y in to equation (1) to get,
This implies that
We divide both side by 3 to get,
