-8 - 5n = 64 + 3n
+5n +5n add 5n to both sides, 5n's cancel out on the left.
______________
-8 = 64 + 8n
-64 -64 subtract 64 on both sides, 64's cancel out on the right.
______________
-72 = 8n
___ ___ divide 8 on both sides, 8's cancel out from the right.
8 8
n= -9, final answer
Just plug in 350 for 'm':


Multiply:
B
The answer is b. Because you x can be a negative, but you’re squaring it so it will equal a positive, and if you add 4, it is still 4 or greater
This is a function because each input has exactly one output ❤️
F(x) = (x + 3)²
g(x) = f(x) - 7.
g(x) = (x + 3)² - 7
g(x) = (x + 3)(x + 3) - 7
g(x) = x*x + x*3 +3*x + 3*3 - 7
g(x) = x² + 3x + 3x + 9 - 7
g(x) = x² + 6x + 2
