Just add the lowest and the highest when u get that answer try multiplying that number that you added by 5,000
Ummmm I’m not sure but ya
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>
Answer:
13n - 39 = 39
Step-by-step explanation:
Let the number be n. Then we have 13n - 39 = 39
