A. The area of a rectangle with a width of 3 units and a
length of x + 5.

3x+15

Step-by-step explanation:

If your width is 3 and your length is x+5, you need to combine those and do 3(5+x) carry your three and multiply it by 5 and x. This will give you 3x+15. You did not give a value for x but if you know x then plug it in and multiply it to 3 then add 15.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
