Area: , Perimeter:

Step-by-step explanation:

a)

We know that for any rectangle the area is , where is the length and is the width.

Because the width is and the length is , the area is or .

b)

We know that for any rectangle the perimeter is , where is the length and is the width.

Because the width is and the length is , the perimeter is .

So, the answers are

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
