The sum of twice a number and another number is 24. the difference of twice the first number and the other number is 12. which system would model this situation, and what is the solution? . a.. 2(x + y) = 24. 2(x – y) = 12. solution: (9, 6). b.. 2x + y = 24. 2x – y = 12. solution: (9, 6). c.. 2(x + y) = 24. 2x – y = 12. solution: (6, 9). d.. 2x + y = 24. 2(x – y) = 12. solution: (6, 9)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
