if it is 2(x+12=27*6-120
x is 9
if it is really
2x+12=27*6-120
x is 15
Hope that helps
An integer is defined as whole number, or a number that is not a fraction. Any whole number that is negative or positive can be an integer. Technically, not all negative numbers are integers. If the number is not a whole number, it is not considered an integer. For example, -2.5 is not an integer.
1. multiply to -18 add to -17
2. multiply to 36 add to -13
3. multiply to -24 add to -5
4. multiply to -18 add to 7
5. multiply to -36 add to 9
6. multiply to 24 add to 10
7. multiply to 18 add to -9
8. multiply to -36 add to -16
thanks!

Answer:
see explanation
Step-by-step explanation:
This is a quadratic equation
Rearrange into standard form : ax² + bx + c = 0 : a ≠ 0
subtract 20e from both sides
25e² - 20e + 4 = 0 ← in standard form
This is a perfect square of the form
(a - b)² = a² - 2ab + b²
25e² = (5e)² ⇒ a = 5e and 4 = 2² ⇒ b = 2, and
- 2ab = - 2 × 5e × 2 = - 20e, hence
25e² - 20e + 4 = (5e - 2)²
⇒ (5e - 2)² = 0 ⇒ e = with multiplicity 2
