A 5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the
width and length of the photograph. Which expression represents the perimeter of the frame?

step-by-step explanation:

in which figure is point g a centroid

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

nope.   happens to me as well.

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
