Question

A hotel manager is adding a tile border around the​ hotel's rectangular pool. Let represent the width of the​ pool, in feet. The length is 5 more than 3 times the​ width, as shown. Write two expressions that represent the perimeter of the pool which exspressions are right

2(4p+5)
8p+5
8p+10
4p+5
4(p+3p+5)
2p+3p+5

im almost out of points plss help

Answer 1

2(4p+5)

8p+10

Explanation:

to understand this

you need to know about:

• algebra
• creating algebraic expression
• PEMDAS

tips and formulas:

• parameter of rectangle:2(l+w)

let's solve:

let width be p

according to the first condition

The length is 5 more than 3 times the width

therefore

the length is

3×p+5

3p+5

Parameter of a rectangle

=2(l+w)

=2(3p+5+p)

=2(4p+5) {combine like terms}

=8p+10{distribute 2}

Answer 2

• A and C

Explanation:

• Width = p
• Length = 3p + 5

Perimeter:

• 2(w + l) =
• 2(p + 3p + 5) =
• 2(4p + 5) =
• 8p + 10

Correct options are A and C
