Step-by-step explanation:

1a. Just add both of them.

8x - 3 + 4x + 5 = 12x + 2

1b. We just subtract both of the functions.

(8x - 3) - (4x + 5) =

4x - 8

1c.

(8x - 3)(4x + 5)

32 {x}^{2}  + 28x - 15

1d.

\frac{8x - 3}{4x + 5}  = 2 - \frac{13}{4x + 5}

An order is written for 1200 adult weight 164 pounds and is 5/9 all with a BSA of 1.9 m to the physician ordered o n c o v i n 2
Kaylis [27]

Answer:

The volume per dose that the patient should receive is 3.8 ml

Step-by-step explanation:

The physician ordered oncovin 2 mg/m² for chemotherapy treatment of a malignant tumor.

The adult's BSA (Body surface area) = 1.9m²

Hence, the amount of oncovin needed based on his body weight is:

2mg/1 m² = x mg/1.9m²

Cross Multiply

x mg = 2mg × 1.9

x = 3.8mg

We are told , oncovin is supplied:1 mg/ml

Hence:

This means

1 mg = 1 ml

3.8 mg = x ml

Cross Multiply

x ml = 3.8 ml

The volume per dose that the patient should receive is 3.8 ml
