Question

b) 1 - x' is equal to​

Answer 1

Answer:

x is a substitution of a value

Step-by-step explanation:

if you take a triangle there are three sides 1st side is 1x 2nd side is 2x 3rd side is 3x then sum of three sides =180 degrees then

1x+2x+3x=180 degrees

6x=180 degrees

x=180/6

x=30

2x=60

3x=90

then,

30+60+90=180 degrees

1×30=30

2×30=60

3×30=90

Answer 2

Answer:

That would depend on what x equals. For instance, if x equals 6, then this would equal 6–1, or 5. The value of x is not a constant in mathematics. Rather it is called a variable, and is used as a placeholder for an unknown value. So unless you know what x is equal to, x-1=x-1.
