What is this 5n+6+(−7n)

Answer:

-2n + 6

Step-by-step explanation:

Combine like terms (terms with the same amount of variables).

Note the laws of signs:

Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.

One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.

Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.

First, change the expression to signify how you should combine the terms:

5n + 6 + (-7n) = 5n - 7n + 6

Combine like terms:

(5n - 7n) + 6

-2n + 6

-2n + 6 is your answer.

A dog sits at a corner of a square with side length 44 meters. the dog runs 10 meters along a diagonal toward the opposite corne
wlad13 [49]

Refer to the figure given below while reading the solution.

Suppose the dog reaches position A when traveled 10 m diagonally towards the opposite side.

And then position B when traveled 5 m towards the right turning 90°.

We can observe that APC is a right triangle with legs of equal length AC. And the coordinates of the point A is (AC, AC).

Also we can observe that APB is a right triangle with legs of equal length AD. Then the coordinates of the point D is (AC, AC-AD).
Hence, the coordinates of B will be (AC+AD, AC-AD).

Now, we since we have the coordinates we can calculate the shortest distances of B from each of the sides.

  1. The shortest distance of B from PQ = AC-AD
  2. The shortest distance of B from SR = 44-(AC-AD)
  3. The shortest distance of B from SP = AC+AD
  4. The shortest distance of B from RQ = 44-(AC+AD)

So, the average of the shortest distances of B from each side is \frac{(AC-AD)+44-(AC-AD)+(AC+AD)+44-(AC+AD)}{4}=\frac{44+44}{4}=22

Hence, the average of the shortest distance of B from each side is 22 m
