Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.
I’m not sure but when I check it show 6
For my estimate I think you need 5 rulers for the door. 7 rulers for the flag. and for the small room wall i:ll say 9 12-inch rulers. :)0
The system of equations has no solution.
Solution:
Given expression –x + 5y = 5 and x – 5y = 5.
–x + 5y = 5 – – – – (1)
x – 5y = 5 – – – – (2)
Adding (1) and (2), we get
–x + 5y + x – 5y = 5 + 5
Combine like terms together.
(–x + x) + (5y – 5y) = 5 + 5
0 + 0 = 25
There is no x-term and y-term in Left hand side.
So, the system of equations has no solution.
