Answer:

(5x-6)²=25x²-60x+36

Step-by-step explanation:

We use: (a-b)²=a²-2ab+b².

Thus we get

(5x-6)²=25x²-60x+36

Find u in terms of m,g and v in this equation E = m/2g(v²-u²)<br>

igor_vitrenko [27]

Step-by-step explanation:

E = m/2g(v²-u²)

2g×E = 2g×m/2g(v²-u²)

2Eg = m(v²-u²)

2Eg = mv² - mu²

mu²= mv² -2Eg

mu²/m = mv² -2Eg /m

u²= v² -2Eg

u = √v²-√2Eg

Logx+log(x-1)=log(4x)

andrew11 [14]

$log( {x}^{2} - x ) = log(4x) \\ {x}^{2} - x = 4x \\ {x}^{2} - 5x = 0 \\ x(x - 5) = 0 \\ x = 0 \\ x - 5 = 0 \\ x = 5$
Since logs can't equal zero, 5 is your only solution.
