Answer:
Our number is 7.
Step-by-step explanation:
We also know that it's 2x + 21 = 5x.
Now we solve.
21 = 5x - 2x
21 = 3x
7 = x
5 x 5 is your answer
Have a great day
15 * 15 * 15 * 500 = 1,687,500. it's different from finding 45 * 500 because
15 * 15* 15 * 500 is the same as writing it as 15^3 * 500. This meaning you multiply the number 15 by itself 3 times, not add it 3 times, which is what
45 * 500 was showing. I hope this helped.

Step-by-step explanation:
The zeroes of the given polynomial is 1 and -6.
<h3>What is Polynomials?</h3>
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
Here, given equation;
f(x) = (x - 1)(x + 6)
for finding the zeros of the equation we need to put.....f(x) = 0
0 = (x - 1)(x + 6)
x - 1 = 0 or x + 6 = 0
x = 1 or x = -6
Thus, The zeroes of the given polynomial is 1 and -6.
