Please help! enter a range of values for x:

myrzilka [38]

Answer:

Step-by-step explanation:

using sine formula

let ∠ADB=y

then ∠CDB=180-y

∠DAB =180-(35+y)

$\frac{AB}{sin~y} =\frac{12}{sin ~35}} \\AB=\frac{12 sin y}{sin 35} \\\frac{BC}{sin(180-y)} =\frac{4x-4}{sin 20 } \\\frac{BC}{sin y} =\frac{4x-4}{sin 20} \\BC=\frac{(4x-4)sin y}{sin 20} \\But~AB=BC (given)\\\frac{12 sin y}{sin 35} =\frac{(4x-4)sin y}{sin 20} \\\frac{4x-4}{sin 20} =\frac{12}{sin 35} \\4(x-1)=\frac{12 sin 20}{sin35} \\x-1=\frac{3 sin 20}{sin35} \approx 1.789\\x \approx 2.789$

Multiply and simplify: (6x + 3y)(6x − 3y)

nasty-shy [4]

Answer:

36x² - 9y²

Step-by-step explanation:

We see that the given expression (6x + 3y)(6x - 3y) looks just like the expression (a + b)(a - b). When multiplied out, this is a difference of squares identity that I highly recommend you memorise:

(a + b)(a - b) = a² - b²

Here, a = 6x and b = 3y, so plug these in:

(6x + 3y)(6x - 3y) = (6x)² - (3y)² = 36x² - 9y²
