Answer:
5(2z +9)
Step-by-step explanation:
factor out 5 of 10z +45
The answer is A. if you divide 620 by four you would get 155 and the rest would have a decimal
They can earn 5$ because that is an average amount for dogs
Congruent means that they are identical
looking at the order of the letters in the triangles EF are the last 2 and QR are the last 2
so EF should equal QR
we are told QR = 10 so EF needs to equal 10
so we have 6y+4 = 10
now solve for Y
6y +4 = 10
subtract 4 from each side:
6y = 6
divide each side by 6
y = 1
Answer:
Rational exponents are not defined when the denominator of the exponent in lowest terms is even and the base is negative.
Step-by-step explanation:
Considering the expression
Here:
A rational exponent - an exponent that is a fraction - is the kind of way we may write a root.
If the denominator is an even number, it means we are talking about an even root like square root, 4th root, 6th root etc.
For example, think about squaring a number
-4 × -4 = 16, 4 × 4 = 16
It means any number when it get multiplied by itself an even number of times, it would always yield a positive number.
It is not possible to take the square root of a negative number as we can not yield a negative number when we square the number. In other words, there is no way we can multiply the same negative number twice and get a negative number. This is why is undefined.
Therefore, rational exponents are not defined when the denominator of the exponent in lowest terms is even and the base is negative.
