Answer:
The product of (x-3) and (x+7) is x² + 4x - 21
Step-by-step explanation:
The product of (x-3) and (x+7) is x² + 4x - 21
The product of (x - 3) and (x + 7) can be found as follows:
(x - 3)(x + 7)
open the bracket by multiplying
Therefore,
x(x) +x(7) - 3(x) - 3(7)
x² + 7x - 3x - 21
combine like terms
x² + 4x - 21
It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
29035 is a positive and -36198 is a negative
Answer:
it could be any number less then 9 so examples would be 8,7,6,5,4,3,2,1 so on so forth
