Answer:
<u>The correct answer is A. 1.5w² + 5w + 4</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the portrait = 1.5 times its width in inches
Frame = 2 inches all along its perimeter
2. What is an expression for the area of the framed portrait in terms of w?
Let's recall that the area of a rectangle is length or height * width.
A = height * width
Now, we can replace in terms of w:
A = 1.5w * w
But we need to add the 2 inches of the frame, this way:
A = (1.5w + 2) * (w + 2)
A = 1.5w² + 2w + 3w + 4
<u>A = 1.5w² + 5w + 4</u>
<u>The correct answer is A. 1.5w² + 5w + 4</u>
If I am not mistaken it is D.

Answer:
both triangles area:
4.2 x 8.2 = 34.44
you don’t need to divide by two cause there’s two triangles anyways.
also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)
rectangle:
4.2 x 5.3 = 22.26
the total area is 56.7cm squared
30 60 90 triangles have a peculiar theorem to them. That’s why they’re known as special right triangles, and they’re super easy to solve. For whatever the length of the shortest side is, which we’ll call Z in this case, the length of the hypotenuse is always 2*Z, and the length of the adjacent side is always Z * sqrt3. In the context of this problem, that means that y = 16 and x = 8sqrt3.
Answer:
![P=\frac{1}{8}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
You're given your variables, you just need to put them in the correct spot. X is on top, and x =1, replace x with 1. Y is on the bottom and y=8, replace y with 8.
