The first step for solving this expression is to multiply each term in the parenthesis by 10w. 10w × 5 + 10w × 4w³ - 10w × 2w Calculate the product of 10w × 5 50 + 10w × 4w³ - 10w × 2w Calculate the product of 10w × 4w³ 50 + 40 - 10w × 2w Lastly,, calculate the final product of -10w × 2w 50 + 40 - 20w² Since you cannot simplify any further,, the correct answer to your question will be 50 + 40 - 20w².

He can go 3/5 of a mile in 1/4 of an hour. 1/2 of an hour is twice that of 1/4 of an hour so all you have to do is double the 3/5 3/5+3/5= 6/5 or 1 1/5 miles alternatively you can just multiply by two, 3/5*2/1=6/5 or 1 1/5 miles
