A rectangular garden is fenced on all sides with 252 feet of fencing. The garden is 6 feet longer than it is wide. Find the length and width of the garden.

Step-by-step explanation:

L = w+8

P = 2L + 2w

256 = 2(w+8) + 2w

256 = 2w + 16 + 2w

256 = 4w + 16

240 = 4w

w=60

Length is 60+8 = 68

width is 60

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

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
