The length of a rectangle picture is 5 inches more than three times the width. Find the dimensions of the picture of it's perimeter is 74 inches.

Length = 29 inches

width = 8 inches

Step-by-step explanation:

perimeter of a rectangle= p =2*L+2*w

L= Length

w = width

we have from the statement:

L= 5+3*w

p=74

so we have:

74 =2*(5+3*w)+2*w

74= 10+ 6w +2w

74-10=8w

64=8w

w = 64/8

w =8 inches = width

so L= 5+3*(8)

L= 5+24

L= 29 inches = Length

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
