Answer:

$2x + 6$

Step-by-step explanation:

$7 - (2x + 1) + 4x$

Distribute the negative inside 2x+1

$7 - 2x - 1 + 4x$

Remind that negative multiply negative must equal positive.

variables cannot sum/add/subtract with constants.

They must be the same terms.

$4x - 2x - 1 + 7 \\ 2x + 6$

Therefore, our answer is 2x+6

Step-by-step explanation:

Given that,

A sequence 352,345,338.

First term = 352

Common difference = 345-352 = -7

We need to find the 37th term of the sequence.

The nth term of an AP is given by :

$a_n=a+(n-1)d\\\\a_{37}=352+36\times (-7)\\\\a_{37}=100$

So, the 37th term of the sequence is 100.

Step-by-step explanation:

What is the solution to this equation?

6 * (x - 5) = 4x + 20

6x - 30 = 4x + 20

2x = 20 + 30

2x = 50

x = 50 : 2

x = 25

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

check

6 * ( 25 - 5) = 4 * 25 + 20

6 * 20 = 100 + 20

120 = 120
