Answer:
Our fourth number is 52.
Step-by-step explanation:
Let our first even number be <em>x</em>.
Then the second even number must be (<em>x</em> + 2), the third (<em>x</em> + 4), fourth (<em>x</em> + 6), and the fifth (<em>x </em>+ 8).
They sum to 250. Hence:

Solve for <em>x</em>. Combine like terms:

Subtract 20 from both sides:

And divide both sides by five. Hence:

Thus, our sequence is 46, 48, 50, 52, and 54.
Hence, our fourth number is 52.
A. The answer is 6$ because 3 x 2 is 6
B. The answer is 12
To find the average rate of change, use the following formula:

a and b represent the values of the interval:

Simplify the original equation by combining like terms:


Plug the interval values into the f(x) equation:


Plug in these values into the average rate of change formula:

The average rate of change over this interval is
-11.
Answer:
no
Step-by-step explanation:
because if you do the math if you do 215 x 48 in doesn't reach to 12000 at all.
