Find two numbers that add to -4 and that multiply to -21.
After playing around with some numbers, I got -7 and 3.
So, the factored form is (x - 7)(x + 3).
Answer:
1) 64
2) 8
3) 2187
4) 5
5) 4
6) 12
7) 9
8) 
9) 27
10) 
11) 4b
12) 
Step-by-step explanation:
Factor r 4 t 4 out of 5 r 8 t 5 − 3 r 4 t 4 . r 4 t 4 ( 5 r 4 t − 3 )
Answer:
x = 
Step-by-step explanation:
2x – 4 – (x + 2) = 6x is the given equation
Now simplifying both sides, we get
2x - 4 - x - 2 = 6x
taking like terms on each side of the equality, we get
2x - x - 6x = 4 + 2
or, -5x = 6
or x = 
hence, the value of x = 
Answer:
The first one is correct.
The second one is also correct!
