Answer:
2x
Step-by-step explanation:
[8x² - 4x] ÷ [4x - 2]
[4x(x - 2)] ÷ [2(x - 2)]
[2x × 2(x - 2)] ÷ [2(x - 2)]
2x
Do you want a proof or just the answer?
The answer is: the square (2.5x2.5).
Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
