Answer:
2x² + 6x - 4
Step-by-step explanation:
f(x) - g(x)
= 3x² + x - 3 - (x² - 5x + 1) ← distribute
= 3x² + x - 3 - x² + 5x - 1 ← collect like terms
= 2x² + 6x - 4
Answer:
x=-1
Step-by-step explanation:
-4(-5x+2)-3x-5=-30
open the bracket
+20x-8-3x-5=-30
collect like terms
20x-3x-8-5=-30
17x=-30+13
17x= - 17
divide both sides by 17
x= -1
I’ve had this question before, it’s C
The answer is $0.8
200/160=1.25
200+160=360/1.25/160=200.8
so the answer is $0.8
