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
Domain is (-infinity, infinity)
Range is [8, infinity)
Answer:
the last one or say there one or more solutions
Step-by-step explanation:
11a = 18a + 21
11a - 18a = - 18a + 21
-7a = 21
7a = -21
a = -21/ 7
a = -3
You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5.
which would be 25/5 which estimates to 5.
