The answer would be B. Ft3 (cubed)
A) Could be -7 + 5 and you'd represent that with 7 negative signs with 5 positive signs.
B) That's already an addition problem, and how'd you represent that is with 5 negative signs and 7 negative signs.
C) That's already an addition problem, and how'd you represent that is with 5 negative signs and 7 positive signs.
D) Could be -5 + 7, and you'd represent that with 5 negative signs and 7 positive signs.

Answer: (y-2)(y-7)</h3>
=====================================================
Explanation:
To factor this, we need to find two numbers that
- A) multiply to 14 (last term)
- B) add to -9 (middle coefficient)
Through trial and error, you would find that the two numbers are -2 and -7
-2*(-7) = 14
-2 + (-7) = -9
So that's why the given trinomial factors to (y-2)(y-7)
You can use the FOIL rule to go from (y-2)(y-7) back to y^2-9y+14 again.
if you have lets say 1/2/2/3
you flip the second fraction and multiply across
1/2*3/2
3/4
.75
Answer:
5/8
Step-by-step explanation:
The longest lizard there is, is 3/4 feet. The shortest lizard is 1/8. The equation to solve this is 3/4 - 1/8. The answer to this is 5/8. I hope this helps :)
