13/99 can't be simplified any further, because 13 is a prime number, meaning that 13 has only 2 factors 1 and itself.
The change would start off as a negative and end as a positive she would end up with $425
if you have a graphing calculator (i use a website called desmos) put in x < 3. i attached a photo of what the graph should look like. the shaded area is where the solutions are. since the shaded area ends with a dotted line, points on that dotted line are <u>not</u> part of the solution.
i hope this helps! sorry i couldn't give a more descriptive explanation... it's pretty much all in the picture lol. have a lovely day! <3
So we should first start off by checking for the ones with the same area, which is 72sq cm
80×90=7200sq cm so A is incorrect
8×10=80sq cm so B is incorrect
3×24=72sq cm so, so far C is correct
4×14=56sq cm so D is incorrect
And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter
24+24=48
48+3=51
51+3= 54
So the perimeter is different, making C the correct answer
