The perimeter of a shape is the length of all the sides added together. In this problem, the length of the rectangle is x and the width is (2x-5). With the information given, we want to show that it equals or is equivalent to (6x-10), which is supposed to represent the perimeter of the rectangle.
Before I write my equation I what to make sure you understand that there are of course two side lengths of this rectangle and two widths. That being said, the equation would look like this:
2x + 2(2x-5) = 6x-10
(both side lengths) + (both widths) = perimeter
I'll show you how you can simplify this equation to show that the perimeter of the field is 6x-10 :
2x + 2(2x-5) = 6x-10
(first step would be to distribute the 2 into 2x-5)
2x + 4x-10 = 6x-10
(add the x's on the left side to simplify)
6x-10 = 6x-10
Well well, what do we have here :). We ended up with the same expression on each side of the equal sign. We totally know that they're equivalent, in fact they're the same.
(I honestly really hope this helps. I confused myself a little thinking a lot about this problem. Please let me know if you run into any issues with my answer. I'm pretty sure I'm accurate on the work I showed. I also wasn't able to view your PDF sadly :( )
You can see a common ratio between the terms of the sequence.
Start with 3.
If you multiply that by -1/3, you get -1.
Multiply -1 by -1/3 again and you get 1/3.
Clearly, the common ratio is -1/3.
Thus, the sequence is geometric.
2) Start with -2, and continue to multiply it by -5/2.
1: -2
2: 5
3: -25/2
4: 125/4
Thus, the answer is d.
Answer:
The answer to your question is y=-3x+14
Step-by-step explanation:
The correct answer is the first choice. 4k^4
74A52B1 and 326AB4C are multiples of 3.....That means if we divide them by 3, we should get a whole number.
Lets assume A=1 and B=1,
So,
74A52B1 becomes 7415211
Now, lets divide it by 3.
7415211 / 3 = 2471737
Since we got a whole number as a quotient, we can safely say that A=1 and B=1.
∴ The second number 326AB4C becomes 326114C.
Now, lets assume C = 1.
So,
326114C becomes 3261141.
Now,
lets divide it by 3.
3261141 / 3 = 1087047
Since we got a whole number as a quotient, C = 1
∴The value of C is 1. So, answer <u>choice A</u> is correct.
