Answer:
it means positive 5. because negative + negative = positive or you can think like -1 times -5 which is 5.
Step-by-step explanation:
Answer:
500 is the answer god bless you
42x can be factored into 7(6x), and 49 is square, meaning it can be factored into 7 squared. I believe the factored expression would be 7(6x + 7) because 7 is the greatest common factor between both numbers.
Answer:
5(9x + 2y + 10)
or
x = 0
y = -5
Step-by-step explanation:
If you are just factoring this, you will factor a 5 out from everything.
5(9x + 2y + 10)
or if you are trying to solve just isolate one of the variables and then substitute it into the original equation
45x + 10y = 50
10y = 50 - 45x
y = 5 - 4.5x
45x + 10(5-4.5x) + 50
45x + 50 - 45x + 50
x=0
45(0) + 10y + 50
0 + 10y + 50
10y + 50
10y = -50
y = -5
and it would be x = 0 and y = -5
