A rectangular vegetable garden is (x+3) feet wide and (2x+7) feet long. Part A: Write an expression for the number of feet of fencing that is needed to completely enclose the garden. Justify your answer.
Part B: Let x=5. How many feet of fencing are needed?

ratio is 2 : 9

the answer is three

13.5 : 3

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

3

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
