Answer:
The answer is 5a-35.
Step-by-step explanation:
So, since you told me to explain, if a number is right next to a parentheses without any signs you multiply it.
But instead of doing 5 times 7a, you multiply both of them separately.
5 times a is pretty much just 5a. 5 times -7 is -35.
As a result, you will be left with 5a-35.
If you have anymore questions, let me know.
Answer:
x^5/6 + 2x^7/3.
Step-by-step explanation:
x^1/3 ( x^1/2 + 2x^2 )
= x^(1/3 + 1/2) + 2x^(1/3 + 2)
= x^5/6 + 2x^7/3
Answer:
a1 = 39, a2 = 41, a3 = 43
The pair with the greatest sum is a2 + a3 = 41 + 43 = 84
Step-by-step explanation:
Let the first integer be a1 = a.
Let the second odd integer be a2 = a + 2
Let the third odd integer be a3 = (a + 2) + 2 = a + 4
The sum of three consecutive odd integers is 123.
123 = a1 + a2 + a3
123 = a + (a + 2) + (a + 4)
123 = 3a + 6
117 = 3a
a = 39
a1 = a = 39
a2 = a + 2 = 39 + 2 = 41
a3 = a + 4 = 39 + 4 = 43
The pair with the greatest sum is a2 + a3 = 41 + 43 = 84
