Answer:
63j
Step-by-step explanation:
Multiply 2j by 9 and 5j by 9. This gets you to 18j+45j. Then, add these since they are like terms: 63j.

Answer:
The two lines of reflection are 
and 
Step-by-step explanation:
I will attach a file with the graph of the rectangle and the lines of reflection.
We know that RSTU is a rectangle with vertices at 
, 
,
and 
The first step is to draw the vertices on the plane and them the rectangle.
The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.
Given that we have a rectangle whose width is 
and its length is 
its centroid will be place at 
.
Looking at the graph and using this information we find that the two lines of reflection are and .
Answer:
A
Step-by-step explanation:
A linear term a variable to the power of one. but there is none of those so theres is no linear term. A quadratic term is a variable to the power of 2, there is one of those so our quadratic term is x^2. A constant term is a term with no variable, thats -7. Our answer is A.
Answer: (-5)¹¹ of (-5)^11
Step-by-step explanation:
Since the base of the two exponents are teh same at -5, we can subtract the exponents.
5-(-6)=11
Now, we know that the new exponent will be 11, with the base staying the same.
