tell whether the sequence is arithmetic. if it is, what is the common difference? -19,-11,-3,

Every next number is incremented by 8 from the previous number hence the sequence is arithmetic and the common difference is 8.

Hope this helps.

35-60 students are taking math.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
