A boy purchased(bought) a party length sandwich 59 in long. He wants to cut it into three pieces so that the middle piece is 6in
Leviafan [203]
Ok so let's start with what we know- the shortest piece is 8 inches so there's one length... then the middle piece is 6 inches longer than the shortest (6+ 8) so the middle piece would be 14 inches long. To find the last piece we can add up the other two pieces we know (14+8) which would be 22 and subtract that from how long the whole sandwich is (59-22) which would be 37 inches long. So in the end he shortest piece would be 8 inches, the middle 14 inches and the longest 37 inches.

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?
Lapatulllka [165]

<u>Answer:</u>

g (h (x) ) = 5/8

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find the value of g ( h ( - 3 ) ):

g ( x ) = \frac { x + 1 } { x + 2 }

h ( x ) = 4 - x

Firstly, we need to find the function :

g ( h ( x ) ) = \frac { ( 4 - x + 1 ) } { ( 4 - x - 2 ) } = \frac { 5 - x } { 2 - x }

Now substituting the value x=-3 in it:

g ( h ( x ) ) = \frac { 5 - (-3) } { 2 - (-3) }

g (h (x) ) = 5/8
