sum means to add
b+57 is the correct expression
hope this helps
3p=p(1+0.06)^t
3=1.06^t
Log(3)=t*log(1.06)
T=log(3)/log(1.06)
T==18.9 years
The numbers are 25 and -15.
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
