Answer:

-21

Step-by-step explanation:

7 * 3 = 21 normally, right?

this equation is the same thing, you just have to make it negative!

for the future, remember that positive * negative = negative answer and negative * negative = positive answer. if you remember that, all you have to do is solve the equation normally and then add a negative sign!

You are knitting a blanket. You want the area of the blanket to be 24 feet squared . You want the length of the blanket to be 2
Sauron [17]
Think of it this way: x multiplied by a number that is two more than x is y.
So, look at the factors. 3 and 8 wouldn't work, because 8 is 5 longer than 3. 1 and 24 wouldn't work, because 24 is 23 more than 1. 12 and 2 is also not going to work; 12 is 10 more than 2. What you have left is 4 and 6. 6 is 2 more than 4, and they both multiply to get 24.

So, the correct answer is 6 feet long and 4 feet wide.
