Answer:
x = 19
Step-by-step explanation:
To find the value of x, you set the equations as equal to each other:
Then you simplify:
To be divisible by 63, it must be divisible by both 7 and 9, since 7x9 = 63. Factor the expression, simplify, and see if both 7 and 9 are factors, which would make it divisible by both 7 and 9. (163 - 83)(43 + 23) = [(24)3 - (23)3] [(22)3 + 23] = (212 - 29)(26 + 23) = [29(23 - 1)] [23(23 + 1)] = [29(8 - 1)] [23(8 + 1)] = 29(7) 23 (9) = 63(212) It is a multiple of 63, and hence divisible by 63.

Answer:
d: (11×7) - (6 + 10)
Step-by-step explanation:
"the product of 11 and 7" is 11×7.
"the sum of 6 and 10" is (6 +10).
The difference between the product and the sum is ...
(11×7) -(6 +10) . . . . . matches choice D
