Question

qro a conta e a resposta

Answer 1

1) b = 20  m = 16  a = x =?

b² = a . m
20² = x . 16
400 = 16 x
- 16 x = - 400 . ( - 1)
16 x = 400
x = 400/16
x = 25
===========================================================
2) m = 3,6    n = 10  h = x = ?

h² = m . n
x² = 3,6 . 10
x² = 36
x = a raiz quadrada de 36
x = 6
