the last one because 7*3=21 14*3=42 and 21*3=63
That's not true. 56 is 10 more than 46. 46 +10 is 56.
Answer: No Real Answers
Step-by-step explanation:
1. Distribute
4x-8=4x+10
2. Get variables to one side add 8, subtract 4x)
0 = 18
3. Since this statement is false, the answer is... No real answers
A. -3x+5+7-4x
-3x-4x+5+7
-7x+12
-7x+12-5x+17
-7x-5x+12+17
-12x+29
B. -5*(x+2)= -5x-10
-6x-1+ (-5x-10)= -6x-5x-1-10=
-11x-11
23 is less than 25 which means it's closer to 20, so you would round it down to 20. 1.75 is over 0.50, 1/2, so you would round it up to 2. If you multiply 2 and 20 you would get 40.
Number two gets the same explanation just with different numbers.
