The side length of a square is represented by the expression 2x + 5. Which expression represents the difference between the area
musickatia [10]

Answer:

4x^2 + 22x + 15

Step-by-step explanation:

The side length of a square is represented by the expression 2x + 5.

The area of a square is given as:

A = a^2

where a = length of side of the square

The area of the square is therefore:

A = (2x + 5)^2\\\\A = (2x + 5)(2x + 5)\\\\A = 4x^2 + 20x + 25

The perimeter of a square is given as:

P = 4a

The perimeter of the square is therefore:

P = 4(2x + 5) \\\\P = 8x + 10

The difference between the area of the square and the perimeter of the square is:

4x^2 + 30x + 25 - (8x + 10)\\\\4x^2 + 30x + 25 - 8x - 10\\\\4x^2 + 30x - 8x + 25 -10\\\\4x^2 + 22x + 15

The expression that represents the difference between the area and the perimeter of the square is:

4x^2 + 22x + 15

A child weighing 22.5 kg has an IV order for Vancomycin Calculate the q8h per dose dosage if the label states that
vodka [1.7K]

Answer:

q8h dosage = 112.5mg

Step-by-step explanation:

Given

Child Weight = 22.5 kg

Daily Intravenous Dosage = 40mg/kg

Type of Dose = q8h

Required

Calculate the q8h per dose

We start by calculating the total daily dosage in mg

This is calculated by multiplying the child weight by the intravenous dosage

Daily Dosage = 22.5kg * 40mg/kg

Daily Dosage = 900mg

This implies that the body weight requires 900 mg daily

Next is to calculate the q8h dosage

q8h means every 8 hours.

q8h dosage = 900mg/8

q8h dosage = 112.5mg
