The sum of three consecutive even integers is 54. Find all three integers.
matrenka [14]
A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'. 
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20

kaheart [24]

Answer:

$7.25 at part-time job

$9.00 every time lawn mowed  

       so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing.  And 41.37  hours to get $300 and he would have to use x and y graph to find the boundary line.

Given g(x)=x^2 and h(x)= x-3 find (g ∘ h)(x)
DerKrebs [107]

Answer:

<h2>(g ∘ h)(x) = x² - 6x + 9</h2>

Step-by-step explanation:

g(x) = x²

h(x) = x - 3

To find (g ∘ h)(x) substitute h(x) into g(x) that's for every x in g(x) replace it with h(x)

That's

(g ∘ h)(x) = ( x - 3)²

= x² - 3x - 3x + 9

We have the final answer as

<h3>(g ∘ h)(x) = x² - 6x + 9</h3>

Hope this helps you
