What statement is true?

14/21 > 17/24
18/32 > 16/32
20/15 < 28/23
29/35 < 20/30

Step-by-step explanation:

We need to find which statements are true.

Solution to find the same we will solve each statement and will conclude the same.

1.  

Now On solving we get;

So we can see that 0.70 > 0.66

Hence The given statement is False.

2.

Now On solving we get;

So we can see that 0.5625 > 0.5

Hence The given statement is True.

3.  

Now On solving we get;

So we can see that 1.33 > 1.2

Hence The given statement is False.

4.  

Now On solving we get;

So we can see that 0.82 > 0.66

Hence The given statement is False.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
