Answer:
1.06
Step-by-step explanation:
This log is to the base 5.
Write 5 5
and then raise the first 5 to the power log5(x + 5)
and the second 5 to the power x^2:
log5(x + 5) x^2
5 = 5
Then we have x + 5 = 5^(x^2)
We can approximate the solution by graphing x + 5 and 5^(x^2) as two separate functions and then reading off the approximate x-coordinate of the point of intersection. The calculator indicates that this coordinate is approximately 1.06 (which matches the fourth answer choice).
(n + 7) (n - 2)
n(n - 2) + 7(n - 2)
n^2 - 2n + 7n - 14
n^2 + 5n - 14
Answer:
58
Step-by-step explanation:
All three angles of a triangle have to add up to 180. Given this we can do the following problem:
180-34-88 = 58
