Answer:
If its a specific shape then probably the formula would be different.
If it were to be a parallelogram then multiply all given lengths
2 x 2 x 3 = 12cm
Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
I want to say it's A? Write a direct variation equation to represent the cost?...
[EDIT]: I am sorry, I thought those were answer choices! Apologies! :)
Answer:
A = 16
Step-by-step explanation:
subtract .5 for both sides --> .25a = 4.5 - .5
.25a = 4
now divide .25 by both sides
A = 16
