Find thetwo consecutive integers whose product is 24

malfutka [58]

Answer:

There is no solution to this equation that is an integer for x.

Step-by-step explanation:

x is the first integer, and x+1 the second

$x(x+1) = 24\\x^{2} + x - 24 =0\\$

$x = \frac{-1+\sqrt{1^{2}+4*24}}{2} =\frac{-1+\sqrt{97}}{2}\\x = \frac{-1-\sqrt{1^{2}+4*24}}{2} =\frac{-1-\sqrt{97}}{2}$

17/13 = y/10 solve for y and round to the nearest tenth

11Alexandr11 [23.1K]

$\frac{17}{13} = \frac{y}{10}$

$17 \times 10 = y \times 13$

$170 = 13y$

$y = \frac{170}{3} = 56.6666....$

56.6666... to the nearest tenth is <u>57</u>.
