Answer:
(3x-5)*(3x-5)
Step-by-step explanation:
Perfect square trinomial is defined by the follow way

Now we can rewrite
as
because a squared add is equal to multiply the add by itself one time
if we make a=3x and b=-5 we can see tha the first answer is the only option that could be a perfect square triomial
Answer:
whats equivelent to 6x4?
Step-by-step explanation:
6 x 4 = 24
8 x 2 = 16 so 8 x 3 = 24 because 8 x 4 would be
8 x 2 = 16
16 x 2 =
6 + 6 = 12
carry the one.
2
1 + 1 + 1 (We now have three ones from carrying that 1) and our answer is
32.
So N = 3
<span>To find the confidence interval, add and subtract the margin of error from the mean.
With mean 18.7 and margin of error 5.9, you have 95% confidence the answer is between 12.8 and 24.6.</span>

Step-by-step explanation:
1.5r+15=2.25r
First of all, you have to arrange the numbers according to those similar to them. So that will be;
15=2.25r-1.5r
1.5r is subtracted from 2.25r because it crossed over an equality sign to get its position close to 2.25r. And when a number crosses over an equality sign, the sign on the number chages to the opposite. 1.5r has an invisible positive sign which became negative when it crossed. Anyway;
2.25r-1.5r is the same as 2.25-1.5. And that is 0.75r
Therefore;
15=0.75r
To find out what r is, you have to divide the both sides by 0.75. This is done to remove the 0.75 close to r to finally reveal what r is. Anyway;
15/0.75=0.75r/0.75
15 divided by 0.75 is 20. And 0.75r divided by 0.75 is r. So;
20=r
r=20. So the answer is 20 movies. Hope i helped. Have a nice day.
