Answer:
B
Step-by-step explanation:
It's a right triangle, so the pythagorean theorem will be used a lot.
First, find the side length on the left.
25^2 = 7^2 + y
y = 24
Now, knowing that 7 - 3 = 4 (the smaller side length), I can use this theorem again to find x.
4^2 + 24^2 = x^2
x = 
Just need to simplify it a little farther...
592 / 16 = 37, so B must be the answer.
Answer:
Step-by-step explanation:
The 12th term is gotten by replacing ń in the equation with 12. Hence,
a(12)= - 5+6(12-1)
Solving the bracket first by BODMAS,
a12= - 5+6(11)
Opening the bracket,
a12=-5+66
a12=66-5
a12=61
3 I think. If there is a graph shown that would help.
