Are you trying to solve for what number goes in the blank space?

Answer 2

Idk

Answer 3

Let's assume so. :P
We can replace the blank space with a variable. Let's use the letter b.
54*46 = 54*6 + 40b
First simplify the left side. What's 54*46?

Answer 4

324

Answer 5

That's 54*6, so now we have...
54*46 = 324 + 40b
How about 54*46? :)

Answer 6

2484

Answer 7

will one of you guys help me with my problem when your done?

Answer 8

Right!
2484 = 324 + 40b
Now we'll combine like terms by subtracting 324 from both sides.
2484 - 324 = 324-324 + 40b
2484 - 324 = 0 + 40b
2484 - 324 = 40b
What's 2484 - 324? :)

Answer 9

Answer 10
