the only 2 numbers that multiply together to make 9 are either 3 and 3 or 9 and 1, neither of which make 7. however, if it's being used in a quadratic the answer you could be looking for is (x-1)(2x+9). hope this helps!

Can you find area by adding?
You can, if you have a square with side 5 you can multiply 5*5=25 or you can add 5+5+5+5+5=25 If you want to do this just take one of the numbers and add it to itself the other numbers times. so if you have 7*8 you add 7 to itself 8 times, so add 8 7's 7+7+7+7+7+7+7+7=56 or add 7 8's 8+8+8+8+8+8+8=56 Multiplying is much easier.
