Answer:
=g-1(4)
Step-by-step explanation:
x=3y+8 ---> y=
y=

First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse =
<span>
<span>
<span>
15.62 feet
Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
</span></span></span>hypotenuse² =
15.62² + 8²
hypotenuse² =
244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.
Answer:

Step-by-step explanation:
Scalene triangle are the triangle with no side are equal in length also each angle have different measure.
As given there are two scalene triangle, which are similar.
∴ Side of both the triangle will be propotionally equal.
Scale is given for both the triangle, which is 5:2.
We know, scale factor= ratio of the side.
Looking the option provided, we see 
As the sides of both the triangle is propotionally equal
Hence,
.
