So first to find the value of x you would set up the equation 486 = (6x)x because the area of a rectangle is equal to length times width. So I did length (6 times the width (6x)) times width (x) equals the area (486). You then solve by distributing, so you get 486 = 6x², then divide by 6 to get 81 = x². You then square root to get x = 9. Then you find the length and width values. Length is 6x, so 6(9) or 54. Width is x so width is 9. Then the perimeter is length + width + length + width or 54 + 9 + 54 + 9 or 126. The perimeter is 126.

grandymaker [24]

Answer:

0.8333

Step-by-step explanation:

Given :

Mean, X = 100

Lower Specification Limit, LSL = 100 - 10 = 90

Upper Specification Limit, USL = 100 + 10 = 110

Standard Deviation, σ = 4

The process capability index, Cpk;

Cpk = Min[(X - LSL) / 3σ; (USL - X) /3σ]

Cpk = Min[(100 - 90) / 12 ; (110 - 100 ) /12]

Cpk = Min [0.8333 ; 0.8333]

Hence, Cpk = 0.8333

Helpppppppppp please
eduard

You know b=-6 and since you know this, you can plug -6 in for b.

This would become 4(-6) + 6 divided by 6.

You can then multiply 4 and -6 together,

-24 + 6 / 6

You can then add -24 and 6 together,

-18/6

You can then divide -18 by 6,

-18/6=-3

-3 is your final answer
