Answer: find the answers in the explanation.
Step-by-step explanation:
Given that the predicted Number of Text Messages Sent = 60 – 0.8 • Age
Where the slope = - 0.8
The intercept = 60
1) the slope of the least regression line is -0.8
2.) The unit of the slope of the line is text per year
3.) Therefore, the slope of the line tells you that for every year older the smart phone user is, you can expect a typical average in text messages sent of - 0.8
4.) The y - intercept of the least square regression line is 60
5.) The unit of the y - intercept of the line are text sent
6.) The y - intercept of the line tells you the starting point. The first number of text messages sent.

Answer:
I'm guessing this is a square. You need to fix your question, anyways:
The area of a square is b(h).
15(10) = 150cm^2.
Your area is 150cm^2
Note that 150 is not squared, only the unit is because we took area.
So what you would do is 8/5 + 4 x 7 = 26.9
then you round it to 30
