Find the length and width of a similar rectangular screen if the length is 5 meters more than 6 times its width, and the viewabl

Sliva [168]

Answer:185 m , 60 m

Step-by-step explanation:

Given

Length is 5 m more than 6 times its width

Suppose width is $x$

So, length is given by $6x+5$

The area is given by $l\times b$

Put values of length and width

$\Rightarrow (6x+5)x=5550\\\Rightarrow 6x^2+5x-5550=0\\$

On solving the quadratic equation, we get $x=30$

Length is $6\times 30+5=185\ m$

Width is $x=30\ m$

the functions f and g are defined as follows f(x)=-5x+2 g(x)=3x^2-3x find f(g) and g(-2) simplify your answer as much as possibl

daser333 [38]

Answer:

f(g) = -15x^2 + 15x + 2.

g(-2) = 18.

Step-by-step explanation:

f(g) = -5(3x^2 - 3x) + 2

= -15x^2 + 15x + 2.

g(-2) = 3(-2)^2 - 3(-2)

= 12 + 6

= 18.
