Answer:
Sophie factored completely.
Carlos did not factor out a 2 out of his last term
Step-by-step explanation:
-4x² − 10x + 6
Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).
If you look at the last term in Carlos
(x + 3)( -4x + 2)
You can factor out a -2
(x+3) (-2)(2x-1)
It is not factored completely with the negative two inside the parentheses
He could also have factored out a 2
(x+3) (2)(-2x+1)
I like having a positive x so I use the -2
Either would be acceptable.
2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
Answer:
C
Step-by-step explanation:
+0.2 will increase every y-value by 0.2, hence shifting the graph 0.2 units upwards
1) =
2) <
3) RS and AB
4) RS and DC are both parallel
