Answer; c^2 = a^2 + b^2
c = 17 inches
a = 8 inches
b^2 = c^2 – a^2
b^2 = 17^2 – 8^2
b^2 = 289 – 64
b^2 = 225
b = square root of 225
b = 15 inches ≈ c.
7x-4x=10-1
3x=9
3/3x=9/3
x=3
A square pyramid has 5 sides.
hope this helps!
25 miles and 5 miles because you only multiply two sides to find the area 25•5=125
