Answer:
8 or 9
Step-by-step explanation:
Your primary equation that they gave you is ?b and has to be greater than ?a 7 x ?a =42
So your answer to ?a is 7 because 7 x 7 =42 therefore your answer to ?b has to be 8 or above.
the next part of your problem states that it is a whole number UNDER 10.... this limits your possible answer to either 8 or 9.
See attached for the synthetic division table
The numbers in the bottom row are 1, 9 and 0
The last number is the remainder. So the remainder is 0
The other values in the last row (1 and 9) form the quotient, so we have 1x+9 = x+9 as the final answer
Final Answer: C) x+9
