(x - 4)/(x + 4)

Step-by-step explanation:

$\begin{aligned}\tt\frac{x^2-16}{x^2+8x+16}&=\tt\frac{x^2-4^2}{\left(x+4\right)^2}\\&=\tt\frac{\left(x+4\right)\left(x-4\right)}{\left(x+4\right)^2}\\&=\tt\frac{x-4}{x+4}\end{aligned}$

The width of the rectangle is five feet less than the length. If the perimeter of the rectangle is 34 feet find both dimensions

Lyrx [107]

Answer:

length = 11 ft, width = 6 ft

Step-by-step explanation:

Let w be the width, l be the length and p the perimeter. You can write down the following equations:

1. w = l - 5

2. p = 2*(w + l)

Now you have two equations with two unknown.

Plugging eq.1 in eq.2:

p = 2*(l-5 + l)

p = 2*(2*l - 5)

p = 4*l - 10

Remember p = 34

34 = 4*l - 10

4*l = 44

l = 11

Using eq.1 to solve for w:

w = 11 - 5

w = 6

If a child accidentally swallowed 1.6 fluidounces of FEOSOL Elixir, containing 2/3 gr of ferrous sulfate per 5 mL, how many mill

GuDViN [60]

Answer:

the amount of ferrous sulphate child will digest = 213.3 mg

Step-by-step explanation:

Given,

Amount of FEOSOL Elixir swallowed by child = 1.6 Fluid ounces

= 1.6 x 29.57 ml

= 47.312 ml

$\textrm{Amount of ferrous sulphate contained in 5 ml of of solution}=\ \dfrac{2}{3}\ grams$

$\textrm{So, amount of ferrous sulphate contained in 1 ml of solution}\ =\ \dfrac{2}{3\times 5}$

$=\ \dfrac{2}{15}$

$\textrm{So,the amount of ferrous sulphate contained in the 1.6 ml of FEROSOL}=1.6\times \dfrac{2}{15}$

$=\ \dfrac{3.2}{15}$

= 0.2133 gram

= 213.3 mg

So, the amount of ferrous sulphate child will digest = 213.3 mg
