A^2-b^2=(a+b)(a-b)
1: x^2-4=(x+2)(x-2)
2: (x+8)(x-8)
3: (x+10)(x-10)
4: (x+14)(x-14)
Answer:
x = -7
Step-by-step explanation:
Given:
5 – x = 12
Subtract 5 from both sides
5 – x - 5 = 12 - 5
- x = 7
Note: the coefficient of -x is -1
- x = 7
Divide both sides by the coefficient of -x
- x / -1 = 7 / -1
x = -7
Check
5 – x = 12
5 - (-7) = 12
5 + 7 = 12
It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value

Since the length of the original painting is 108 inches, you take 1/12 and multiply it by 108 and get 9 inches.
the length of Sammy's drawing is 9 inches.
Step-by-step explanation:
sin = 15/17
