Answer:
It can be 23 or 823
Step-by-step explanation:
Depends because if you divide 138 and 6 you'll get 23.
If you multiply 138 times 6 you'll get 823
The answer is the last option (Option D), which is:
D. 25
The explanation is shown below:
1. You have that:
(a ± b)^2=a^2 <span>± 2ab + b^2
2. The expression given in the problem is:
</span><span>x^2-10x+n
Where x^2=a and 2ab=10x
2b=10
b=10/2
b=5
3. Therefore, you have:
b^2=5
b^2=25
b^2=n
n=25</span>
Answer:
The leghts of AB is 9 because both of the triangles are symmetrical. But also, this is a Equilateral triangle, which means that both of the sides are the same lengths (AB=AC)
Answer:
its b
Step-by-step explanation:
M=slope
b=y-intercept
y and x are coordinates
hope this helps, that is a much as I can give you with this little of information
