steposvetlana [31]

Answer:

The expression for the perimeter of the rectangle is: P = 4x - 18

Step-by-step explanation:

Perimeter of a rectangle:

A rectangle has length l and width w. It's perimeter is given by:

P = 2(l + w)

In this question:

l = x - 9, w = x

So

P = 2(x - 9 + x) = 2(2x - 9) = 4x - 18

The expression for the perimeter of the rectangle is: P = 4x - 18

one pair of parallel lines : AB and DC

one pair of equal angles : <em>L</em><em> </em>A and <em>L</em><em> </em>D

4. (7²× 3`¹)⁴×7^5 / (3² × 7^(-6))³

= (7^8 × 3`⁴)×7^5/ (3² × 7^(-6))³

= (7^13 × 3`⁴)/ (3^6 × 7^(-18))

= (7^(31) × 3^(-10))

= 7^31 / 3^10
