The width of a rectangle is modeled by the function w(x) = 3x – 6, and the length of the rectangle is modeled by the function l(

x) = 5x + 7. How can the functions be combined to find a function, a(x), that models the area of the rectangle?
a(x) = 8x + 1
a(x) = 16x + 2
a(x) = 15x2 – 9x – 42
a(x) = 30x2 – 18x – 84

Mekhanik [1.2K]

Answer:

1/2

Step-by-step explanation:

Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.

The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.  

The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.

Please help!!!! BRAINLIEST for whoever is correct!! What is the difference of the rational expressions below?
Nostrana [21]

Answer:

<h2>\frac{3x + 25}{5 {x}^{2} }</h2>

Step-by-step explanation:

\frac{x + 5}{ {x}^{2} }  -  \frac{2}{5x}

Write all the numbers above the least common denominator {5x}^{2}

\frac{5(x + 5) - 2x}{5 {x}^{2} }

Distribute 5 through the parentheses

\frac{5x + 25 - 2x}{5 {x}^{2} }

Collect like terms

\frac{3x + 25}{5 {x}^{2} }

Hope this helps...

Good luck on your assignment...
