5 h – 9 = – 16 + 6 h Add 9 to both sides 5 h – 9 + 9 = – 16 + 6h + 9 5 h = – 7 + 6h Subtract 5 h to both sides 5 h - 5 h = - 7 + 6 h - 5 h 0 = - 7 + h Add 7 to both sides 0 + 7 = - 7 + h + 7 7 = h h = 7 Proof : 5 h – 9 = – 16 + 6 h 5 * 7 - 9 ...

math
8 ( n - 3 ) / 3 = 32 Multiply both sides by 3 8 ( n - 3 ) = 96 Divide both sides by 8 n - 3 = 12 Add 3 to both sides n = 15

calculus
a. When x = sqrt ( 5 ) f ( x ) = 10 x ^ 2 / ( x ^ 4 + 25 ) = 10 * sqrt ( 5 ) ^ 2 / ( sqrt ( 5 ) ^ 4 + 25 ) = 10 * 5 / ( 25 + 25 ) = 50 / 50 = 1 yes b. When x = 3 f ( x ) = 10 x ^ 2 / ( x ^ 4 + 25 ) = 10 x ^ 2 / ( x ^ 4 + 25 ) = 10 * 3 ^ 2 ( 3 ^ 4 + 25 ) = 10 * 9 / ( 81 + 25 ) ...
