Answer:
x=18
Step-by-step explanation:
Triangles add up to 180°, so 140+22+x=180 and then you simplify which is 162+x=180, then you subtract 162 on both side, getting x=18
Step-by-step explanation:
Simplify the following expression then state the property used:
9^-2
Property:
Given,
9^-2
For any real numbers a and b a, b ≠ 0, and for any two positive integers, n and n
a^-m
=> 1/a^m [By doing reciprocal]
So,
9^-2
=> 1/9^2
=> 1/(3^2)^2
=> 1/(3^4)
=> 1/(3*3*3*3)
=> 1/81. Ans.
Hope this helps.
Equation A:= True and has an infinite number of solution and B: is False no solution exists thus d: is your Answer.
