Answer: n⁴+10n²x+25x²

Step-by-step explanation:

I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.

(n²+5x)²                           [rewrite this from the squared]

(n²+5x)(n²+5x)                [use FOIL to expand]

n⁴+5n²x+5n²x+25x²       [combine like terms]

n⁴+10n²x+25x²

5. While still in the hospital, the doctor writes an order for an antibiotic at 300mg/kg daily. You are nervous now because the
Scilla [17]

The correct answer is 16737 mg

Explanation:

The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:

123 lb x 0.453 = 55.791 kg

Now, simply multiply the kilos by the recommended dose:

55.791 kg x 300 mg/kg = 16737 mg

Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)

16737mg ÷ 1000 =  16.737 grames

sweet-ann [11.9K]

Answer: C, D

<u>Explanation:</u>

Length: L = x + 3

width: x ≥ y + 2   ⇒  y ≤ x - 2

wheels: y

0.50(L * x) + 4(2.25y) ≤ 50

0.50(x + 3)(x) + 4(2.25y) ≤ 50

0.50(x² + 3x) + 9y ≤ 50

                        9y ≤ 50 - 0.50(x² + 3x)

                        <u>9y</u> ≤ <u>50 - 0.50x² - 1.5x</u>

                        ÷9               ÷9

                          y ≤ \frac{50}{9}-\frac{1}{6}x-\frac{1}{18}x^{2}

*******************************************************************************

15 per person is the rate

22 is the constant

y = 15x + 22

<em>divide that by the number of people (x) to get:</em>

y = \frac{15x + 22}{x}
