Answer: <em>3</em>
Step-by-step explanation:
<em>Take your equation x-1=2</em>
<em>Now put 3 in for x</em>
<em>3-1=2</em>
<em>2=2</em>
<em>x=3</em>
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.
