I am big pp lol xD hxyjdrh
Answer: X = 4
Step-by-step explanation: To solve for k in this equation, we want to get k by itself on the left side of the equation.
Since k is being multiplied by 5, to get k by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out, so we are simply left with z. On the right side, we have 20 divided by 5 which gives us 4.
Now we have X = 4.
Finally, remember to check your answer by substituting a 4 back into the original equation.
So we have 5 (4) = 20 which is a true statement.
This means that our answer, x = 4 is correct.

The Binomial Theorem is a quick way (okay, it's a less slow way) of expanding (or multiplying out) a binomial expression that has been raised to some (generally inconveniently large) power. For instance, the expression <span>(3x – 2)10</span><span> would be very painful to multiply out by hand. Thankfully, somebody figured out a formula for this expansion, and we can plug the binomial </span><span>3x – 2</span><span>and the power </span>10<span> into that formula to get that expanded (multiplied-out) form.</span>
The formal expression of the Binomial Theorem is as follows:
