Answer:

$1) - 2n + 14$

$2)- 5n + 30$

Step-by-step explanation:

$n = a + (n - 1) \times d \\ = 12 + (n - 1) \times - 2 \\ = 12 - 2n + 2 \\ = - 2n + 14$

$n = a + (n - 1) \times d \\ = 25 + (n - 1) \times - 5 \\ = 25 - 5n + 5 \\ = - 5n + 30$

A square has a perimeter of 40 m what is the length of each side

zubka84 [21]

Answer:

10m

Step-by-step explanation:

Perimeter means adding up all of the sides of a shape.

One property of a square is that all lengths of a square are the same.

We also know squares have 4 sides.

Lets set up an expression to solve the length for each side with variable S representing the length of a side:

4 * S = 40

Divide each side by 4:

S = 10

Therefore, each side of the square has a length 10m
