The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
The range is the set of all the y or in your case values that g(x) can have
Domain is
X= {0, 1, 2, 3, 4}
Range is
Y= g(x)= { g(0)=3, g(1)=0, g(2)=3, g(3)=12, g(4)=... }
Since they both have the same variables, just add the numbers and get 13. So therefore it is 13x
