The answer is B for this problem
2(x+3)=7(3x-2)
2x+6=21x-14
Estimation involves rounding
3/8 is closest to 4/8 which is 1/2, or 6/12
6/12 + 1/12 = 7/12
that is the estimated answer
Find how much the tree grew by subtracting the original height from the new height:
49 1/2 - 38 1/2 = 11 feet.
To find the average yearly rate, divide the amount the tree grew by the number of years:
11 feet / 5 1/2 years = 2 feet per year.
<h2>
Answer:</h2>
A - Both speed and velocity are changing.
<h2>
Step-by-step explanation:</h2>
Though the answer is option A but option D can also be true. The velocity cannot be completely determined from the graph. This is because, velocity is based on the direction and motion and the graph is not completely justifying this.
Though velocity cannot be determined, but it is clear from the graph that velocity is changing, because the speed is changing.
Therefore, option A is completely true.
