For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.
Step-by-step explanation:
In order to prove the statement we can take any value of x and then solve the expression to see if it equal to -16 or not.
So,
Taking x = 2

Taking x = 5

Taking x= 10

Hence,
For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.

Answer:
1/6 i think
Step-by-step explanation:
so if the first die is 2 and then a die has 6 sides it would be a 1/6 chance of rolling a 5
Answer:
n = -13
Step-by-step explanation:
19 + 10n = 7n - 20
Subtract 7n from each side
19 + 10n-7n = 7n-7n - 20
19+3n = -20
Subtract 19 from each side
19+3n -19 = -20-19
3n = -39
Divide each side by 3
3n/3 = -39/3
n = -13
