Given that f(n) = n^2 - 4n + 3 & g(n) = 2n - 1 find gf(-2)

icang [17]

Answer:

The value of $gf\left(-2\right)$ will be:

$gf\left(-2\right)=29$

Step-by-step explanation:

Given the functions

$f(n) = n^2 - 4n + 3$

$g\left(n\right)\:=\:2n\:-\:1$

$f\left(-2\right)\:=\:\left(-2\right)^2\:-\:4\left(-2\right)\:+\:3$

$=\left(-2\right)^2+4\cdot \:2+3$

$=2^2+4\cdot \:2+3$

$=2^2+8+3$

$=4+11$

$=15$

$gf\left(-2\right)=g\left(15\right)$

$=2n-1=2\left(15\right)-1=30-1=29$

Therefore,

$gf\left(-2\right)=29$

A rectangles width is 13 more than its length. If the perimeter is 82 feet what is the length and width.

docker41 [41]

Answer:

Step-by-step explanation:

Lenght should be the greater here. I am considering your question however.

Let length side is 'x'.

The width side is 'x +13'

Perimeter of a rectangle : 2 ×( length + width)

given that perimeter is 82

2 × ( x + x + 13) = 82

2 × ( 2x + 13) =82

4x + 26 = 82

2x = 56

x = 28 cm

length is 28

width is 41
