Answer: lenght is 50yrds, width is 30yrds

Step-by-step explanation:

Perimeter of a pool = 2( lenght x breadth)

Perimeter = 160yrds

If the lenght is 10yrds less than twice the width then,

lenght = 2w - 10,

Where w is the width

Then from p = 2(L + w)

160 = 2( 2w - 10 + w)

160 = 2(3w - 10)

160 = 6w - 20

160 + 20 = 6w = 180

width w = 180/6 = 30yrds

From p = 2(L + w)

160 = 2(L + 30)

160 = 2L + 60

160 - 60 = 2L = 100

L = 100/2 = 50yrds

A rectangle has sides measuring (2x + 7) units and (5x + 9) units. Part A: What is the expression that represents the area of th
andrey2020 [161]

Answer:

Part A:  

(2x+7)(5x+9)

=(2x+7)(5x+9)

=(2x)(5x)+(2x)(9)+(7)(5x)+(7)(9)

=10x2+18x+35x+63

=10x2+53x+63

A)

The formula for determining the area of a rectangle is given as

Area = length × width

Given that the length and width are (2x + 6) units and (5x + 3) units, the expression for the area is

(2x + 6)(5x + 3) = 10x² + 6x + 30x + 18

Area = 10x² + 36x + 18

B)

The degree is 2 because the highest power of the terms is 2. It is classified as a trinomial because it has 3 terms.

C) it is closed under multiplication. the exponents in the polynomials are whole numbers(2 and 1). The whole numbers are closed under addition, which means that the new exponents formed are also whole numbers. The exponents were whole numbers before multiplication and doesn't change after multiplication.

rusak2 [61]
If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50%  convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.
