Answer:
1
Step-by-step explanation:
Three side lengths that meet the requirements of the triangle inequality will form exactly one triangle.
_____
The triangle inequality requires the sum of the short sides be at least as long as the long side. Here, we have 3 + 4.69 = 7.69 > 7, so we satisfy the triangle inequality.
The side lengths can be arranged in clockwise or counterclockwise order, least to greatest. Each triangle is a reflection of the other, so they are considered to be the same triangle (congruent).

It is in between

And

There for it is in between 5 and 6
Additionally, it is closer to root 25, meaning that it is closer to 5
Rounded to the nearest hundredth is
5.29
6y-10=y+25
subtract y from both sides
5y-10=25
add 10 to both sides
5y=35
divide both sides by 5
y=7
It's the value of
when
:

When
, the derivative/slope is 2, so the answer is C.
3 = 48 divided by 16
