Armon specializes in framed art. For a specific design of framed art, the width of the frame is 10 inches longer than the width
dlinn [17]

Answer: The answer is: f(x) = 2x^2 + 40x + 200

Explanation:

Given: x is the width of the Artwork

Let W be the Width of the Frame

Let L be the Length of the Frame

Width = x + 10

Length = Width * 2, so by substitution, Length = 2(x + 10)

Area = Width * Length

By substitution:

Area = (x + 10) * 2(x + 10)

f(x) = (x + 10) * (2x + 20)

f(x) = 2x^2 + 20x + 20x + 200

f(x) = 2x^2 + 40x + 200

To test this, if a picture 8" wide is put in this frame, the width would be 8+10 or 18 inches. The length would be twice the width, or 36 inches. The Area is 18 x 36 = 648.

Using the formula:

f(8) = (2 * 8^2) + (40 * 8) + 200

f(8) = (2 * 64) + 320 + 200

f(8) = 128 + 320 + 200

f(8) = 648

Sherman wants to apply to an animal welfare agency as a photographer. Which kind of photos should Sherman include in his résumé?
Murrr4er [49]
C. Shots of various animals would be the best answer. Since Sherman is applying to an welfare agency as a photographer, the other options wouldn’t make as much sense.


Hope this helps

Ok so. What would you do if ur mom and dad said they ordered your x mas gifts online, buuuttt, that your gifts were not going to
vovangra [49]

Answer:

Well I wouldn’t worry about it. The item will come sooner or later and you probaly won’t use it as much, try to ignore the item and stop watching things and reviews of the item because being impatient for the item to come is just gonna make you think it’s coming slower. but late items are not as late as you think, even during this corona thing. Items that arriving from other countries should take about 1-2 weeks and if its in the same country, d_elivery should be 5-7 days Max. Even with corona, planes aren’t slowed down, they just cut the amount planes but not even by a quarter so plane‘s schedule should usually be on time and if delayed, it shouldn’t make you wait for another week, It should take about 2-3 days. So don’t trust the manufacturer if they
