The answer is C. I hope this helps you.
Answer:
Step-by-step explanation:
a)
- 1.5x² + 6x + * =
- 1.5(x² + 4x + *) =
- 1.5(x² + 2*2x + 4) =
- 1.5(x + 2)²
- * = 1.5*2² = 6
b)
- 2x² - 5x + * =
- 2(x² - 2.5x + *) =
- 2(x² - 2*1.25x + 1.25²)=
- 2(x - 1.25)²
- * = 2*(1.25)² = 3.125 or 25/8
It is equal to 2(x)^3 because pemdas, exponnets come before multiplication so it would be x^3 then multiply whatever that is by 2
2x^3 is answer (4th choice)
<span><u>Answer </u>
=3,075.36 ml
<u>Explanation</u>
We must first convert pounds to kilograms. 1Lbs = 0.453592Kg.
So, 226 Lbs=226×0.453592
=102.512Kg
Now calculate how many ml Mr. Rogers would take.
30ml→1 Kg
What about 102.512 Kg?
102.512Kg→102.512×30
=3,075.36 ml
Since this figure is above the threshold ml per day, then we take the answer as 3,075.36 ml per day.
