Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
Answer:
Erin gets a result number of 5
Step-by-step explanation:
Assuming this is a 'word problem.' -- These are small numbers so you could use your hand for visual. :)
Start with 4 fingers up. (adding a negative to a positive is basically subtraction sooo...) put 3 fingers down. You now have one finger up. (subtracting a negative is just addition, think about taking those two minus signs and putting them together to get an addition sign.) now add 4 fingers to your one finger. You should be left with 5 fingers up!
Hope I helped. Hang in there, it will get easier!
ANSWER
The correct answer is B
<u>EXPLANATION</u>
If we analyse the coordinates carefully, you realize there is a mapping of
This is a reflection in the y-axis.
Since the transformation is a reflection, the shape is preserved. Therefore, the image triangle P'Q'R' of triangle
PQR are congruent.
Answer:
$9$
Step-by-step explanation:
Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.
To find: number that Thea originally entered
Solution:
The final number is $243$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $243$ must be $324$.
As previously the number was squared, so the number before $324$ must be $18$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $18$ must be $81$
As previously the number was squared, so the number before $81$ must be $9$.
Answer:
I'd say D
Step-by-step explanation:
Because it makes the most sense and it is the most notable one.
Correct me if I'm wrong.
Hope this helps :).
