Answer:
x+17
Step-by-step explanation:
Writing this for the sake of adding more characters, but yeah. 'A number' is basically x, add 17....bam! x+17
First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!
48:24 = 24:12 = 12:6 = 6:3 (divide each number by 2 or multiply by 2)
