16x16 is the correct Answer
<span>The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years, the item is worth $551.25. Which equation represents y, the value of the item after x years? idk sorry</span>
There are four rectangles and 2 squares.
Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________
Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2
TOTAL: 392+392 = 784 cm^2
Wow I should have realized the the 4 rectangles are the area as the two squares.
Good luck to you!

Answer:
if the length, width and height of a cube quadruple, then the volume of the cube will be multiplied by 64.
Step-by-step explanation:
Given a cube of width W, height H and length L, the volume of the cube will be: Volume = W*H*L
If all the three parameters quadruple, then:
New Width = 4W
New Height = 4H
New Length = 4L
New Volume = 4W*4H*4L = 64WHL
Therefore, if the length, width and height of a cube quadruple, then the volume of the cube will be multiplied by 64.
Answer:
v=3.2
Step-by-step explanation:
Let's solve your equation step-by-step.
−12.3+7v=10.1
Step 1: Simplify both sides of the equation.
7v−12.3=10.1
Step 2: Add 12.3 to both sides.
7v−12.3+12.3=10.1+12.3
7v=22.4
Step 3: Divide both sides by 7.
7v
/7
=
22.4
/7
v=3.2
