The number that when divided by 12 equals 72 is 864. This is found by multiplying the divisor (12) with the desired quotient (72). Therefore, the answer is 864.
To solve for the number that when divided by 12 gives an answer of 72, we need to leverage the standard division operation in mathematics.
To find this number, we simply multiply 12 (the divisor) by 72 (the quotient). This is the reverse of the division process, also known as multiplication.
When we perform this calculation, 12 multiplied by 72, we find the answer to be 864. Therefore, 864 is the number that when divided by 12 gives you 72.

Answer: x = {-3, -1, 1, 7}
Step-by-step explanation:
f(x) = x⁴ - 4x³ - 22x² + 4x + 21
possible roots are: +/- 1, 3, 7, 21
Let's try x = 1
1 | 1 -4 -22 4 21
| ↓ 1 -3 -25 -21
1 -3 -25 -21 0 remainder is 0 so (x - 1) is a factor
(x - 1)(x³ - 3x² - 25x - 21)
Next, let's try x = -1
-1 | 1 -3 -25 -21
| ↓ -1 4 21
1 -4 -21 0 remainder is 0 so (x + 1) is a factor
(x - 1)(x + 1)(x² - 4x - 21)
Then, factor the third polynomial
(x - 1)(x + 1)(x + 3)(x - 7)
Now, set each factor equal to zero and solve each one.
(x - 1) = 0 ⇒ x = 1
(x + 1) = 0 ⇒ x = -1
(x + 3) = 0 ⇒ x = -3
(x - 7) = 0 ⇒ x = 7
Answer:
-3, -1, 1, 7
Step-by-step explanation:
Evaluate the function at each x value in the choices. If the polynomial evaluates to zero, then that x value is a solution.
f(-3) = (-3)^4 - 4(-3)^3 - 22(-3)^2 + 4(-3) + 21 = 0
x = -3 is a solution
f(-1) = (-1)^4 - 4(-1)^3 - 22(-1)^2 + 4(-1) + 21 = 0
x = -1 is a solution
f(0) = (0)^4 - 4(0)^3 - 22(0)^2 + 4(0) + 21 = 21
x = 0 is not a solution
f(1) = (1)^4 - 4(1)^3 - 22(1)^2 + 4(1) + 21 = 0
x = 1 is a solution
f(3) = (3)^4 - 4(3)^3 - 22(3)^2 + 4(3) + 21 = -192
x = 3 is not a solution
f(7) = (7)^4 - 4(7)^3 - 22(7)^2 + 4(7) + 21 = 0
x = 7 is a solution
