(x+3)^2+4=46
what is the solution of this equation
2 answers:
Step-by-step explanation:
(x + 3)² + 4 = 46
(x + 3)² = 42
x + 3 = ±sqrt(42)
x = ±sqrt(42) - 3
x1 = sqrt(42) - 3 = 3.480740698...
x2 = -sqrt(42) - 3 = -9.480740698...

h = 6 cm
Answer:
Step-by-step explanation:
a1 = 7
a2 = 4(7) = 28
a3 = 4(28) = 112
a4 = 4(112) = 448
a5 = 4(448) = 1792
a6 = 4(1792) = 7168
