Answer:
-8ab - 2a - 7
Step-by-step explanation:
Since you're subtracting/adding I like taking away the parentheses which makes the equation: -2ab - 2a - 5 - 6ab - 2

Answer:
A is not a right triangle
B is a right triangle
Step-by-step explanation:
A.
6^2 = 36
12^2 = 144.
36 + 144 = 180
15^2 = 225
180 ≠ 225, so it is not a right triangle
----------------------------------------------------------------------------
B.
5^2 = 25
12^2 = 144
25 + 144 = 169
13^2 = 169
169 = 169, so it is a right triangle
Answer:
Robert's piece of wire is 5 feet long
and Maria's piece of wires is 7 feet long
Step-by-step explanation:
Suppose x and y are Robert's and Maria's piece of wires respectively.
We can write following equation using this statement "Half of Robert's piece of wire is equal to ⅔ of Maria's wire".
--------------(1)
The total length of their wires is 12 feet.
------------(2)
=> 
Substitute x=12-y in equation (1)




Put y=7 in equation (2)
