Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
The formula of a volume of a rectangle prism:
l - length
w - width
h - height
We have
Substitute:
<h3>Answer: V = (10n³ + 50n² + 20n + 100) in³</h3>
Hello! :))
So all you have to do is <em>add</em> the <em>numerator</em> to get a total of 4/5.
Hope this helps!!
Answer:
(D)
Step-by-step explanation:
Angles 2 & 6 are called corresponding angles in the diagram and they are congruent if the lines c & d are parallel. Since they are, that means lines c & d are parallel.
Hey there! :D
If 20 is 25% of a number,
we know that it is a quarter of a number.
20*4= 80
20 is 25% of 80.
I hope this helps!
