Answer:
C. 1.5w^2 + 7.5w + 9
Step-by-step explanation:
Without frame:
The width is w. The height is 1.5w.
With frame:
The width is w + 1.5 + 1.5 = w + 3
The height is 1.5w + 1.5 + 1.5 = 1.5w + 3
The area of the framed portrait is height * width
area = (1.5w + 3)(w + 3)
area = 1.5w^2 + 4.5w + 3w + 9
area = 1.5w^2 + 7.5w + 9
Answer:
^3sqrt(-27), ^3sqrt(-8), 0, ^3sqrt(8), ^3sqrt(27), sqrt(10), 6, 8
Step-by-step explanation:
You just need to convert these to decimals to figure it out.
In our case
^3sqrt(-27) = -3
^3sqrt(-8) = -2
^3sqrt(8) = 2
^3sqrt(27) = 3
sqrt(10) = 3.16
So...
-3, -2, 0, 2, 3, 3.16, 6, 8
-4.6, -0.7, 4/8
