Jack wants to simplify the expression below.

(6.7x -3) - (3.4x - 1) + (2x - 2)

answer the following questions.

1) how can jack regroup the expression by commutative property?

2) after regrouping in step 1, how can jack further simplify the expression by

distributive property?

3) what is jack's final simplified expression?

5.3x - 4 .

Step-by-step explanation:

(6.7x -3) - (3.4x - 1) + (2x - 2)

1. using the commutative property:

= 6.7x - 3 +  2x - 2 - (3.4x - 1)      (we can remove the parentheses around the first 2 groups because they are added).

2. Using the distributive property on the last group:

= 6.7x - 3 + 2x - 2 - 3.4x + 1   (distributing the negative over the parentheses).

3. Now adding like terms we get:

5.3x - 4 (answer).

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
