Answer:
x^2-1^2
Step-by-step explanation:
formula:
(a-b)(a+b)=a^2-b^2
ANSWER
b=1, c=81, and d=9.
EXPLANATION
The given function is:

This function is the same as:

To find the inverse of this function, we interchange x and y.

Solve for y:

Take square root of both sides:


Hence,
b=1, c=81, and d=9.
7 - 2/ b < 5/b
or, 7 < 5/b + 2/b
or, 7 < 7/b
divide both side by 7
1 < 1/b
or, b < 1
hope i did it correct
The distributive property:
a(b + c) = ab + ac
2(x - 8) = 68
(2)(x) - (2)(8) = 68
2x - 16 = 68 |+16
2x = 84 |:2
x = 42
