Answer:

Step-by-step explanation:

3 3/10=33/10

6 2/3=20/3

-------------------

33/10*20/3=660/30=22

The area is 22 m^2.

------------------------------------

2(33/10)+2(20/3)=66/10+40/3=299/15

The perimeter is 299/15 meters.

Write the subtraction expression as an equivalent addition expression and then evaluate it.

solniwko [45]

The subtraction expression is solved to get -27 gives while the equivalent addition expression is -65 + 35 evaluating gives -47

<h3>What is subtraction and addition?</h3>

Subtraction refers taking away a value from a certain value while addition implies increasing a value by a certain value

<u>Given data</u>

-15 - 12

solving we have

-15 - 12 = -27

equivalent addition

-62 + 35

evaluating the equivalent addition

-65 + 35 = --27

Answer the question with explanation;

PSYCHO15rus [73]

Answer:

The statement in the question is wrong. The series actually diverges.

Step-by-step explanation:

We compute

$\lim_{n\to\infty}\frac{n^2}{(n+1)^2}=\lim_{n\to\infty}\left(\frac{n^2}{n^2+2n+1}\cdot\frac{1/n^2}{1/n^2}\right)=\lim_{n\to\infty}\frac1{1+2/n+1/n^2}=\frac1{1+0+0}=1\ne0$

Therefore, by the series divergence test, the series $\sum_{n=1}^\infty\frac{n^2}{(n+1)^2}$ diverges.

EDIT: To VectorFundament120, if $(x_n)_{n\in\mathbb N}$ is a sequence, both $\lim x_n$ and $\lim_{n\to\infty}x_n$ are common notation for its limit. The former is not wrong but I have switched to the latter if that helps.
