Answer:
Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.
Step-by-step explanation:
They have the same exponent and it is multiplication.
There is a law of exponent that says 
.
So we have 
equals 
.
Let's simplify (4*7)^(-2).
Since 4*7=28, we can say 
.
Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So 
.
Since the 3 and 7 have 21 as a common multiple you can divide 21 by the denominator of each term and then multiply it by the numerator which get you while numbers
Use a protractor to do the problem, but try finding th answer yourself
Answer:
answer is 11.
Step-by-step explanation:
the median is always the middle
Answer:
The solution is x = 10 and x = -6. This quadratic could be represented in factored form as (x - 10)(x + 6) or on a graph with x-intercepts at (10,0) and (-6,0).
Step-by-step explanation:
To solve the quadratic, write the quadratic in standard form and factor the equation.
x² - 4x = 60
x² - 4x - 60 = 0
(x - 10)(x + 6) = 0
x = 10 and x = -6
