Since this is a 45-45-90 triangle, n = 9 and m = x
The answer is C- Distributive Property because you times everything in the bracket by the value connected to it:
9 times 2=18
9 times x = 9x
= 18 - 9x
Negative 3x over the power by four
First figure out what 851 minutes 473 equals to, which is 378
So both sides of the equation should equal to 378
Plus 470 and 378 together
Which equals to 848
So the answer is eight hundred and forty eight
Draw the number line then put the numbers on the number line by twos. Fore example, 2-4-6-8-10
