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
Yes they are because you use distributive property and 4(x+y) you have to do 4•x= 4x and 4•y=4y so it would be 4y+4x
I think by SAS because there is only one angle and two sides
Answer:
Explanation:
P = 2(W + L)
L = 2x - 3
W = x + 4
P = 2[(x + 4) + (2x - 3)]
So thats the expression for the perimeter
Number 39 is 10, number 40 is 7
