Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
The system of equations have 2 solutions
<h3>How to determine the number of solutions?</h3>
The system of equations is given as:
-1/3x² = 5/6 + 1/3y²
5y² = 25/2 - 5x²
Next, we plot the graph of the system of equations.
From the attached graph, the equations intersect at two points
Hence, the system of equations have 2 solutions

Answer:
2.5
Step-by-step explanation:
Multiply 25 by 10 that gives you 250
Divide 250 by 100 which gives you 2.5
6×5 would=30 which is the amount of zebras so if you multiply 5×5 you would=25 which is how much elephants there are
Choice 3
5/2, 15/6 divide by 3 = 5/2. 45/18 divide by 9 5/2
