Answer:
9x + 3 = 7x + 19
Step-by-step explanation:
Given that,
Jeffrey set up chairs for a meeting.
He arranged the chairs in 9 equal rows but had 3 chairs left over.
Let x be the number of chairs. So,
9x+3 .....(1)
Then he arranged the chairs in 7 equal rows but had 19 chairs left over. So,
7x+19 ......(2)
From equation (1) and (2),
9x+3 = 7x+19
9x-7x = 19-3
2x = 16
x = 8
Hence, the correct option is (b).
I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.

Step-by-step explanation:
Answer:
18
Step-by-step explanation:
a^2 + b^2 = c^2

24^2 = 576
30^2 = 900
900 - 576 = 324
the square root of 324 is 18
