28/2 or 28 x (1/2)
You can either divide $28 by 2 or multiply it by (1/2)
Answer:
2
Step-by-step explanation:
f(x) = 3(2) - 4
f(x) = 6 - 4
f(x) = 2
Answer:
Option D
Step-by-step explanation:
Option A
x² - 3x² + 2x² = 0
Therefore, the given polynomial has no roots.
Option B
x² + 2x + 8
By quadratic formula,
x = 
= 
Therefore, roots are imaginary and for a polynomial with degree 1 or more than 1, both the roots can't be imaginary.
So the polynomial can't have exactly two roots.
Option C
99x³ - 33x + 1
Since the polynomial is of degree 3, so it will have three roots.
Therefore, the polynomial will not have exactly 2 roots.
Option D
√2x - 3x² + 7√2
By quadratic formula,
x = 
x = 
There are exactly two real roots.
Therefore Option D is the answer.
Option E
4x + 11x - 111
Since this polynomial is of a degree 1.
There will be only one root.
plain and short, an hour has 60 minutes, and a minute has 60 seconds, therefore an hour has 60*60 or 3600 seconds, and we can express that rate as hr/3600s or the other way around 3600s/hr, depending on which version we need.
a mile has 5280 feet, again, we can use that rate as mile/5280ft or 5280ft/mile, as needed.
