x=4
Step-by-step explanation:
2log(x)+log(5)=log(80)
log(x^2)+log(5)=log(80)
log(5x^2)=log(80)
5x^2 =80
x^2 =80/5
x^2=16 , taking square root both sides
x=√16
=4
45 = (x) + (x + 1) + (x + 2)
45 = 3x + 3
- 3
42 = 3x
/3
14 = x
45 = 14 + (14 + 1) + (14 + 2)
45 = 14 + 15 + 16
The ages of the 3 friends are 14, 15, and 16.

Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,




This pattern can be defined as

Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get

The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
Answer:
The answer is : 2/3
Step-by-step explanation:
2+9x^2=6
9x^2 = 6 - 2
9x^2 = 4
x^2 = 4/9
x = √(4/9)
x = 2/3
