Answer:

Option 4

Step-by-step explanation:

They are matching sides of congruent triangles.

Since AD is parallel to BC,

and AD is equal in length with BC

So therefore a diagonal drawn from A to C forms congruent triangles of ACD = CAB making it a reflexive property of equality

So therefore:

AB is parallel to CD

An arithmetic sequence is given below.

Mashcka [7]

Given that $a_1=24$ and $a_2=17$ , if $a_n$ is an arithmetic sequence, then the common difference between successive terms is $d=a_2-a_1=17-24=-7$ .

You then have

$a_2=a_1+d$
$\implies a_3=a_2+d=a_1+2d$
$\implies a_4=a_3+d=a_1+3d$
$\implies \cdots\implies a_n=a_{n-1}+d=\cdots=a_1+(n-1)d$

So the explicit formula for the $n$ th term is

$a_n=24-7(n-1)$

The city will place a low fence around the entire fish pond.To the nearest hundredth, how long will the fence be?

Tom [10]

You can't tell the dimensions from the area. There are an infinite number of correct answers. The length of the fence is 2 times (length of the pond + width) and the length and width can be anything, just as long as their product is 2956.5 .
