A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is x, then the diagonal is such that

√(2) x = 10 cm

→ x = 10/√(2) cm ≈ 7.07 cm

The perimeter of a square is 4 times its side length, so the perimeter is

4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm

which makes 28.4 cm the closest answer.

How do I slove this eqaution, and whats the answer? -3(n+6)+10=-9

Sauron [17]

Answer:

$n = \frac{1}{3}$

Step-by-step explanation:

Apply the distributed property, so it now looks like this: -3n + -18 + 10 = -9
Combine like terms: -3n + -8 = -9
Simplify: -3n - 8 = -9
Add 8 to each side, so it now looks like this: -3n = -1
Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = 1/3

I hope this helps!

Given the arithmetic sequence with the following two

kondor19780726 [428]

Answer:

aₙ = -15 + 10 * (n-1)

Step-by-step explanation:

aₙ = a₁ + (n-1)*d a₁: first term d: common difference

a₅ a₁ + 4d =25 .... (1)

a₁₁ a₁ + 10d = 85 ...(2)

(2) - (1) 6d = 60

d = 10

a₁ = -15

Formula: aₙ = -15 + 10 * (n-1)
