Plug in -6 for a and -5 for b
3(-6)^2 - 4(-5)
3(36)+20
108+20
=120
Answer:
6m²
Step-by-step explanation:
Because the question asks for the area of a face but it doesn't indicate which face then it can be any of the faces.
2m x 3m = 6m²
2m x 4m = 8m²
3m x 4m = 12m²
In your case one of the possible answers is 6m² - so that is the one they are looking for.
Answer:
1 a. commutative property of multiplication
b. distributive property of multiplication
2 x=23\12
-x = -23\12
-23\12+23\12=0
thus -(-x)+x
