Times the two radicals together
So it's:
8*sqrt 15*5 (find common numbers between 5 and 15 which is 5)
8*sqrt(5^2*3)
8*5 sqrt3
40 sqrt 3
Hope this helped :)
Answer:
No.
Step-by-step explanation:
Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!
90 / 9 does equal 10, but 90 / -9 equals -10.
The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.
Thus, the correct answer should be -10.
Answer:
The first one. Top left.
Step-by-step explanation:
The top right one makes a triangular prism.
I don't even know if the bottom right is even a thing.
The bottom left is a cube.
Answer:
a(n) = -3 - 2(n-1)
Step-by-step explanation:
The most general formula for the nth term of an arithmetic sequence (such as this sequence is) is
a(n) = a(1) + c(n-1), where c is the common difference.
Here a(1) = -3 and c = -2.
Thus,
a(n) = -3 - 2(n-1).
