Answer:

z + 12

Step-by-step explanation:

This is the answer because:

1) Our like terms are 2z and z and 9 and 3

2) First, we should add 9 and 3 because they are like terms and there is a + sign in front of the 3 which equals to 12

3) Then, subtract 2z and z because they are like terms and there is a - sign in front of the z which equals to z

4) Finally, we are left with z + 12. This expression is simplified because there is no more like terms

Hope this helps!

kotykmax [81]

Answer:

3

Step-by-step explanation:

  4 1/2 + 3 1/3 + 2 + 2 1/6

= 4 3/6 + 3 2/6 + 2 + 2 1/6

= 4 + 3 + 2 + 2 + 3/6 + 2/6 + 1/6

= 11 + 6/6

= 11 + 1

= 12

There are 4 numbers, therefore average = 12 ÷ 4 = 3

It is good equation. Look, that:
81 = 3 x 3 x 3 x 3 = 3^4.
So you have to solve:
3^x = 3^4 
exponents have to be the same, so
x=4
That's mean that A(4) = 81

Answer:

The value 4.5 is rational and the value 15−−√ is irrational. The sum of 4.5 and 15−−√ has a non-repeating and non-terminating decimal expansion. Therefore, the sum of 4.5 and 15−−√ is irrational. I can't explan but that's the correct Answer
