A) true
b) false (unless the two numbers have the same absolute value, like -4/4 and -5/5)
c) false
d) false
Answer:
14m^2
Step-by-step explanation:
Area of a triangle is - 1/2 base times hight
two triangels find the srea of both and add them
4x4x1/2 = 16x1/2 = 8m
3x4x1/2 = 12x1/2 = 6m
6m + 8m = 14m
Answer:
The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.
Step-by-step explanation:
P(x,n) is a polynomial of nth degree if it is of the form,
P(x,n) = 
where n is a finite positive integer and n ∈ N
and '
's are fixed but otherwise arbitrary constants ∀ i = 0(1)n .
Now, the given expression is,

which doesn't fit in the above form. Hence, it is not a polynomial.
F(x) = 9x + 5
y = 9x + 5
9x = y - 5
x = (y - 5)/9
f^-1(x) = (x - 5)/9
f^-1(x) is a function.
