Answer:7x-5x+6
Step-by-step explanation:combine all like terms
Answer:
2/9, 2/27
Step-by-step explanation:
54, 18, 6, 2, 2/3
Take the second term and divide by the first
18/54 = 1/3
We multiply by 1/3
Check by taking the third term and dividing by the second
6/18 = 1/3
This works
Take the last term and multiply by 1/3
2/3*1/3 = 2/9
2/9*1/3 =2/27
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
