Explain the mistake. Graham says that he can make this
repeated addition problem, 6+6+8+4,
into a multiplication sentence. Explain
why he can't.

24

Step-by-step explanation:

see the mistake is addition it is supposed to be multiplication like 12(2) or 6(4) or 8(3)

because they are small numbers although he can't make 6684 he can make a 2 digit sentence

Step-by-step explanation:

6+6+8+4=24

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
