Answer:
Step-by-step explanation:
The given equation is
We group the linear terms to get:
We compare to
This means
a=1, b=-6 and c=-10
We plug in the values into the quadratic formula:
This gives us
The solutions are
or
Answer: 152 miles.
Step-by-step explanation: For each hour a train travels 38 therefore if it drove 2 hours it would drive double the distance and so forth.
38 x 4 = 152 miles.
Answer:65
Step-by-step explanation: So the answers would be 78 as well
When changing from radical form to fractional exponents, remember these basic forms:
The nth root of a can be written as a fractional exponent with a raised to the reciprocal of that power.
is taken, it’s raised to the 1/n power. When a power is raised to another power, you multiply the powers together, and so the m (otherwise written as m/1) and the 1/n are multiplied together.
Use fractions in the powers to indicate that the expression stands for a root or a radical.
Leave the exponent as 9/4. Don’t write it as a mixed number.
