Answer:
The answer is 3
Step-by-step explanation:
To get it into standard you need to simplify
6y - 12 = -3x add 12 to both sides
6y = -3x + 12 add 3x to both sides
3x + 6y = 12
And that is in standard which is A + B = C
The answer is 2-7=5 is the answer
Answer:
36
Step-by-step explanation:
Compare what you have to the square ...
(a +b)^2 = a^2 +2ab +b^2
Your "a" is √(25x^2) = 5x
Your "2ab" is -60x. Since you know "a", you can find "b".
2ab = -60x
2(5x)b = -60x . . . . . . . substitute for "a"
b = -60x/(10x) = -6
Then the missing term is b^2 = (-6)^2 = 36.
Your trinomial is ...
25x^2 -60x +<u>36</u>
4x - 4y = -36
3x + 4y = 8
7x = -28
/7 /7
x = -4
-4 - y = -9
+4 +4
-y = -5
/-1 /-1
y = 5
(-4 , 5)
