Long division of polynomials is the same as that of integers.
We find the number that we can multiply (4x + 5y) by to obtain the given polynomial. This is (4x - 5y).
Moreover, this is visible from the fact that
(16x² - 25y²) satisfies the identity:
(a² - b²) = (a + b)(a - b); where a = 4x and b = 5y

sorry I don't know about this....
Hlo sis...
how are u...hope ur fine
Answer:
11: Diameter
13: 10 cm
Step-by-step explanation:
Diameter is a straight line across a circle.
It would be 10 because if you cut 20 in half, which is the whole distance of the line, you would get 10.
Nope! If they were proportional, one would be able to be reduced to the other.
It's like the (however clichéd) example of pie slices! If you cut two pies into 8 and 20 pieces, three pieces of the pie sliced into eight pieces will not be the same as seven pieces of the pie sliced into twenty!
