Answer:
12
Step-by-step explanation:
219-75=144
144%2=12
Answer:
39
Step-by-step explanation:
In order to solve this you have to fond r.
In 3r=18 you divide the 3 from both sides to isolate the variable.
18÷3=6 so you are left with r=6
So r is 6.
Plug that into 6r+3
6(6)+3
6×6=36
36+3=39
Answer: (3t-2)^2
Step-by-step explanation:
Well, multiply 9 and 4 together to get 36.
Now what factors of 36 add to 12? Well, 6 and 6, so let's rewrite this:
9t^2-6t-6t+4
Now group factor what you can:
3t(3t-2)-2(3t-2)
Now 3t and -2 both share the common factor of (3t-2) so you can rewrite it as:
(3t-2)(3t-2) which is:
(3t-2)^2.
Hope that makes sense or helps!
When graphing Y=3X-5 you want to start looking at the Y axis or the vertical line that goes up and down. You need to draw your first point or dot on the vertical line starting at negative five (-5). Then you start to go up 3 boxes and over 1 box or to the right one box because the equation has 3x in it . So after starting at negative 5 you want to travel up 3 and over 1, up three and over 1, do this until your graph can no longer go on or is not bug enough. Did i answer your question?
