The parentheses of the expression (-2+2w+4w)(-7) is removed using the distributive property and the resultant expression is -14-42w.
<h3>What is distributive property?</h3>
The distributive property says that the product of a number and sum of two numbers is equal to the addition of the product of that number with the individual number of the sum.
c×(a+b)=ac+ab
The given expression in the problem is,
(-2+2w+4w)(-7)
Now, use the distributive property to remove the parentheses as,
(-2+2w+4w)(-7)
-2×-7+2w×-7+4w×-7
-14-14w-28w
-14-42w
Hence, the parentheses of the expression (-2+2w+4w)(-7) is removed using the distributive property and the resultant expression is -14-42w.

For this case, the first thing we must do is define variables.
We have then:
n: number of cans that each student must bring
We know that:
The teacher will bring 5 cans
There are 20 students in the class
At least 105 cans must be brought, but no more than 205 cans
Therefore the inequation of the problem is given by:
Answer:
105 <u><</u> 20n + 5 <u><</u> 205
the possible numbers n of cans that each student should bring in is:
105 <u><</u> 20n + 5 <u><</u> 205
Since "a" is on the top and the bottom, you can simplify that
Answer:
The possible length is greater than 29 meters.
Step-by-step explanation:
If the length is x then the width is x - 2 m.
So the perimeter is 2x + 2(x - 2) = 4x - 4 m.
4x - 4 > 112
4x > 116
x > 29 m.
