The value of this is -1 so the answer is B.

Answer: 8 and 9 or -9 and -8
Step-by-step explanation:
Let
be the first of the two integers. Then, since the numbers are consecutive,
is the other integer. We then know that the sum of the squares of
and
is equal to 145. So, now we have the equation

which can be expanded and simplified to

which then gives us the quadratic equation

This can then be factored into

Which can be simplified further into

So either
or
. This gives us two solutions: 8 and 9 or -9 and -8.
Hope this helps! CHEERS!
Question 1
It won't be completely simplified, because 8 can be factored further, so I would say the answer is "no"
A much better factorization would be
sqrt(72) = sqrt(36*2)
since 36 is the largest perfect square factor of 72
If you're curious how it simplifies, then it would do so like this
sqrt(72) = sqrt(36*2)
sqrt(72) = sqrt(36)*sqrt(2)
sqrt(72) = 6*sqrt(2)
Note: "sqrt" is shorthand for "square root"
==============================================
Question 2
For monomials like this, we simply cut the exponent in half, or we divide by 2.
28/2 = 14
Therefore, sqrt(x^28) = x^14
The given expression simplifies to x^14
Answer:
C=9
Step-by-step explanation:
A = πr^2
A = π 9
9
The route will take four hours and fifteen minutes. If you start at 9:50 and count four hours, you'll get to 1:50, add ten to get to 2:00, then add 5 minutes to get to 2:05. Four hours plus ten minutes plus five minutes, 4:15.
