solmaris [256]

Answer:

$-9\dfrac{5}{8}$ inches.

Step-by-step explanation:

The level of a lake was 8 inches below normal.

Now, it is given that the water level decreases $1\dfrac{1}{4} = 1.25$ inches in June and $2\dfrac{3}{8} =2.375$ inches more in July.

Therefore, the new level of water with respect to the normal level will be

= - 8 - 1.25 - 2.375

= - 9.625 inches

= $-9\dfrac{5}{8}$ inches. (Answer)

Divide. Express the quotient in simplest form.

Scorpion4ik [409]

$( \frac{x^2 - x -12}{2x} )$ ÷ $( \frac{x^2 - 2x - 8}{4x^2} )$

= $( \frac{x^2 - x -12}{2x} )$ × $( \frac{4x^2}{x^2 - 2x - 8} )$

= $\frac{x(x^2 - x -12)}{x^2 - 2x - 8}$

= $\frac{x(x^2 -4x +3x -12)}{x^2 -4x +2x -8}$

= $\frac{x[x(x - 4) +3(x - 4)]}{x(x - 4) +2(x - 4)}$

= $\frac{x(x-4)(x+3)}{(x-4)(x+2)}$

= $\frac{x(x+3)}{(x+2)}$
