Answer: 1600

Explanation: If angles E and D are the same with the lines intersecting at B, then that means that A and C are also the same, as the opposite angles formed at point B are also the same, so you have two similar triangles.

Similar triangles have proportional lengths. So we know length CD is 800 ft and its similar leg on the other side (AE) is unknown.

So we need to find two known lengths, one on the large and one on the small, that are similar.

BE is 1400 ft and BD is 700 ft. Those are you two known similar legs. So now we can use them in a proportion to find AE.

We will do the line ending at B over the line that doesn't include B.

Large triangle:

x

1400

​

Small triangle:

800

700

​

Set them up in a proportion:

x

1400

​

=

800

700

​

Solve for x:

⇒7x=11200

⇒x=1600 ft

What type of association is shown by the scatterplot
bulgar [2K]

For this case we have that the figure shown in the graph is non-linear. In addition, it is observed that if the given points are modeled, the figure of a parabola can be obtained, so we can say that the trend is strong.

Thus, a <em>non-linear function</em> with a <em>strong tendency</em> is shown.

Answer:

Option C

Which binomial is a factor of 9x^2+24xy+16y^2
gregori [183]

Answer: (3x + 4y)(3x + 4y)

Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.

Factors of -36 that add to 13
sergij07 [2.7K]
To solve this problem follow the steps below.

Step 1:List out all of the factors for -36

-36: 1,2,3,4,6,9,12,18,36
       -1,-2,-3,-4,-6,-9,-12,-18,-36

Step 2: Start going through a process of guessing and checking (basically take any two factors and add them together to see if they equal 13)

1 plus 12=13
9 plus 4=13

Step 3:Check your calculations and make sure you didn't make any errors

13-12=1 and 13-1=12   
13-9=4    and  13-4=9

Answer: 1 and 12
               4 and 9

I hope this helps and if any false information was given I apologize in advance.
