Answer:
(3x+4)(3x+4) is factor of given expression.
B is correct.
Step-by-step explanation:
We are given an expression 
Formula: 
First we write each term as perfect square as formula.


Using formula , a=3x and b=4

Now we write same number two times.
Hence, (3x+4)(3x+4) is factor of given expression.
Answer: 1+1 = 2 :)
Step-by-step explanation:
You could multiply 19.45 by 0.2 to solve for it, but if you're not using a calculator, then 19.45/5 would be much more convenient and easier.
0.2 is 1/5 in fraction form, which is why we can do that.
19.45/5 = 3.89
Dino should leave $3.89 as a tip.
