What is the difference of the polynomials?
(-2xºy2 + 4x2y3 – 3xy\) – (6x4y - 5x2y3 - 15)
bxy-2x7 + 9x²8 – 3xy + y
-6x*y - 2xy2 - x2y3 - 3xy1 - y
exy + 3x37 + 4x²/3 – 3x + y
bxy-7x7 + 4x²/3 – 3xst – ys

it has to be a.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

answer: h

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
