Answer:

Step-by-step explanation

You must find the common denominator for all of them.

A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.

B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.

C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.

D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.

Can someone pls tell me how to graph to find the solution?

Bas_tet [7]

Answer:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Factor completely 5x2 – 50x + 120

zaharov [31]

The answer is 5(x - 4)(x - 6)

5x² – 50x + 120 = 5*x² - 5*10x + 5*24
= 5(x² - 10x + 24)
= 5(x * x - 4x - 6x + 6*4)
= 5(x(x - 4) - (6x - 6*4))
= 5((x(x - 4) - 6(x - 4))
= 5(x - 4)(x - 6)

Answer:

$2x^{10}y^{12}$

Step-by-step explanation:

$\huge \frac{60x^{20}y^{24}}{30x^{10}y^{12}} \\ \\ = \huge \frac{2x^{20}y^{24}}{x^{10}y^{12}} \\ \\ = \huge 2x^{(20 - 10)}y^{(24 - 12)}\\ \\ = \huge 2x^{10}y^{12}$
