Answer: Aaron was at the sitter for 5 hours
Step-by-step explanation:
12x + 10 = 58
the 12x is for each hour after the first hour and the 10 is the first hour
-10 from each side
12x = 48
/12
x = 4
4 additional hours plus the original hour
Answer:
x = - 7
Step-by-step explanation:
Given
3(x - 4) = 5x + 2 ← distribute left side
3x - 12 = 5x + 2 ( subtract 5x from both sides )
- 2x - 12 = 2 ( add 12 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
Answer:
) +, -
e) x, ÷
g) ÷
Step-by-step explanation:
Rather than carrying out IBP several times, let's establish a more general result. Let

One round of IBP, setting


gives


This is called a power-reduction formula. We could try solving for
explicitly, but no need.
is small enough to just expand
as much as we need to.





Finally,

so we end up with


and the antiderivative is
