Answer:
I believe the correct answer is $10,000. I'm not positive, though.
I mean, this isn't a question but its true?
Answer:
(x +2)(2x +1)
Step-by-step explanation:
The factors are the set of tiles down the left side: x + 1 + 1 = (x +2), and the set of tiles across the top: x + x + 1 = (2x +1)
Your factored form is shown in choice D:
(x +2)(2x +1)
_____
<em>Additional comment</em>
The point of this sort of diagram is to show you how the factors work together to give you the product. Each tile in the middle of the figure represents the product of the tile on the top line and the tile in the left column.
The product of x and x is x².
The product of 1 and x is x.
The product of 1 and 1 is 1.
The product of the two factors is the sum of all the tiles in the middle of the diagram: 2x² +5x +2.
Answer:
3) (0,-4) (4,0) (0,4) (-4,0) 4) (-2.5, 2.5) (5.5) (5.-3)
Answer:
25
Step-by-step explanation:
Those parallel lines tell us our triangles are similar. So that means the corresponding sides are proportional.
So we have that x corresponds to x+15 and
40 corresponds to 24+40.
So we have this proportion to solve:
Let's simplify what we can:
Cross multiply:
Multiply/distribute:
Subtract 40x on both sides:
Divide both sides by 24:
x=25
