a^2 + b^2 = c^2 let a = altitude b = 8 c = 14 a^2 + 8^2 = 14^2 a^2 = 196 - 64 a^2 = 132 a = 11.49

v = s^3 64 = s^3 s = 4 in SA = 6s^2 = 6 x 4^2 = 1024 in^2 Now I know v = 64 in^3 & SA = 1024 in^3 The ratio is 1024/64 = 16:1 is it right????

5x + 4y = 8 x + y = 7 Find x : x = 7 - y 5(7 - y) + 4y = 8 35 - 5y + 4y = 8 -y = 8 - 35 y = 27 x = 7 + 27 x = 34 y = 27 x = 34

9/10 + 6/25 (you have to find the denominator, the denominator is "50") = 45/50 + 12/50 = 57/50 = 1 7/50
