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.
Answer:
Step-by-step explanation:
We have a board that is yards long. If we want to cut the board into 5 <em>equal pieces</em>, we must divide
by 5.
5 is the same thing as , so:
To divide a fraction by a fraction, we multiply by the reciprocal.<em> </em>This means we take the reciprocal of and multiply the two fractions.
The reciprocal of is
- we swap the numerator and denominator.
Multiply the numerator and denominators to get our final fraction:
