If the perimeter of a square is 12cm and you are looking for the length of one side. You divide 12cm by 4 because it is a square and you get 3cm for one of the lengths of the side.

A square has 4 sides.

If the perimeter around the square is 12cm, then you do 12 ÷ 4, which is 3.

Each side is 3cm long.

Find the first 4 terms in each sequence

koban [17]

Answer:

a₁ = -21 (Given)

a₂ = -28

a₃ = -35

a₄ = -42

Step-by-step explanation:

First term a₁ = -21 (Given)

…………………………………

Second term a₂ :

a₂ = $a_{2-1} - 7\\a_{1} - 7\\a_{1} = -21\\-21 - 7 = -28$

…………………………………

Third term a₃ :

a₃ = $a_{3-1} - 7\\a_{2} - 7\\a_{2} = -28\\-28 - 7 = -35$

…………………………………

Fourth term a₄ :

a₄ = $a_{4-1} - 7\\a_{3} - 7\\a_{3} = -35\\-35 - 7 = -42$

Answer with solution

adelina 88 [10]

In general, the scalar multiple of k times u, is this:

 $k\vec u = k(ux, uy)=(Kux,Kuy)$

So, here's how we find $3\vec v$

$3\vec v = 3 * (2,4) = (3*2,3*4) 

= (6,12)$

The answer is (6,12).
