Answer:
All 3 are right triangles.
Step-by-step explanation:
In a right triangle c^2 = a^2 + b^2 where c is the longest side. ( by Pythagoras).
a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27
36 = 9 + 27
So this is a right triangle.
b)
17^2 = 289, 15^2 = 225 and 8^2 = 64
289 = 225 + 64
Also right triangle.
c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25
So also right triangle.
Answer:
A line that passes through (3, -8) and (7,-2).
Denote equation of that line: y = ax + b
=> Slope a can be directly determined by:
a = (7 - 3)/(-2 - -8) = 4/6 = 2/3
=> y = (2/3)x + b
This line passes (3, -8), then: -8 = (2/3)*3 + b => -8 = 2 + b => b = -10
=> y =(2/3)x - 10
There are other ways to find equation of line.

Basically, we need to plug in the given values for the variables
![x](https://tex.z-dn.net/?f=x)
and
![y](https://tex.z-dn.net/?f=y)
into the given expression
![1.3(x+2)-(y-6)](https://tex.z-dn.net/?f=1.3%28x%2B2%29-%28y-6%29)
. First off, we can plug in all the given values into the expression, giving us
![1.3(4+2)-(2-6)](https://tex.z-dn.net/?f=1.3%284%2B2%29-%282-6%29)
. Now, perform the operations on the inside of the parentheses. Doing this, we get
![1.3(6)-(-4)](https://tex.z-dn.net/?f=1.3%286%29-%28-4%29)
. Now, we use the distributive property to simplify. This gives us
![7.8+4](https://tex.z-dn.net/?f=7.8%2B4)
. Finally, when we add the two numbers, we get
![\boxed{11.8}](https://tex.z-dn.net/?f=%5Cboxed%7B11.8%7D)
. Hope this helped!
Answer:
is D
Step-by-step explanation:
for egny
56/25 = 2.24
32.05/15= 2.13666..
If you're looking for a larger value 56/25 is your answer.
