What two numbers add up to 18 and multiply to 80

mestny [16]

Answer:

8 and 10

Step-by-step explanation:

First, let's look at the factors of 80.

1 • 80 = 80

2 • 40 = 80

4 • 20 = 80

5 • 16 = 80

8 • 10 = 80

Look at each pair and evaluate their sum.

1 • 80 = 80

1 + 80 = 81

2 • 40 = 80

2 + 40 = 42

4 • 20 = 80

4 + 20 = 24

5 • 16 = 80

5 + 16 = 21

8 • 10 = 80

8 + 10 = 18

Our last pairing multiplies to 80 and adds up to 18. Therefore, your answer is 8 & 10.

Hope this helps!
