Answer:
2 x (3 y^3 + 2)
Step-by-step explanation:
Simplify the following:
2 x + x + x + 2×3 y y x y
2 y×3 y = 2 y^2×3:
2 x + x + x + 2×3 y^2 x y
2×3 = 6:
2 x + x + x + 6 y^2 x y
6 y^2 x y = 6 y^(2 + 1) x:
2 x + x + x + 6 y^(2 + 1) x
2 + 1 = 3:
2 x + x + x + 6 y^3 x
Grouping like terms, 2 x + x + x + 6 y^3 x = 6 x y^3 + (2 x + x + x):
6 x y^3 + (2 x + x + x)
2 x + x + x = 4 x:
6 x y^3 + 4 x
Factor 2 x out of 6 x y^3 + 4 x:
Answer: 2 x (3 y^3 + 2)
Step-by-step Answer:
A dilation about (0,0) or origin has the rule
(x,y) -> (kx,ky)
where k is the scale factor, (x,y) denotes the preimage, and (kx,ky) denotes the image.
For B(-8,-2), and k=12,
we have
B'(-8*12,-2*12) = B'(-96,-24)
