Answer:
(2,3,4,5)
Step-by-step explanation:
The domain are all real number at x-axis
So the answer is option b (2,3,4,5)
The expression can be solved by expanding the bracket and multiplying out the terms


Therefore, the expression can be simplified as;

Alternatively, using the theorem of difference of two squares, which is

Hence,

Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides

Answer:
-3
Step-by-step explanation:
Divide through the equation by the leading coefficient to obtain:
y+3x-4=0
y=4-3x
and our gradient is -3
