Write the following sentence using mathematical symbols. The sum of 10 and x is -13. "The sum of 10 and x is -13" in mathematical symbols is..

10 + x = -13

Step-by-step explanation:

The sum of 10 and x is -13.

10 + x = -13

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
