3+8+10+14+11= 46
46/(how many trees) 5= 9.2
9.2 years is your answer.
The first question is 2, 12, and 14 but i’m sorry i don’t know the second :(
Answer:
a) -3x^3 - 2x + y - 10 = 0
b) it a trinomial
c) not sure. sorry. :(
hope this helps.:)
The answer is x=7. I hope this helps. Tell me if you need an explanation!
We have that
x²<span> + 3x = 24
</span><span>Group
terms that contain the same variable
</span>(x² + 3x) = 24
<span>Complete
the square. Remember to balance the equation by adding the same constants
to each side
</span>(x² + 3x+2.25) = 24+2.25
Rewrite as perfect squares
(x+1.5)² = 26.25
(+/-)[x+1.5]=5.12
(+)[x+1.5]=5.12----> x=5.12-1.5---> x=3.62
(-)[x+1.5]=5.12-----> x=-1.5-5.12---> x=-6.62
the answer is<span>
3.62, –6.62</span>
