X is less than or equal to 4.
6x2-9x-6 is equal to 66.
9x2-9x-10 = (3x+2)(3x-5) when factored
99.
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
X is less than or equal to 4.
Divide both sides by 9: 9x > 27 → x > 3
Let the numerator be x, so the denominator is x + 4. So we have:x/(x + 4) = 9/15 (cross multiply)15x = 9(x + 4)15x = 9x + 3615x - 9x = 9x - 9x + 366x = 366x/6 = 36/6x = 6x + 4 = 6 + 4 = 10Sine the numerator is 6 and the denominator is 10, then the fraction is 6/10, which in the simplest form is equal to 3/5.Since 9/15 in the simplest form is also equal to 3/5, then 6/10 is equivalent to 9/15.Thus, 6/10 is the required fraction.
-9x - 10 = 62 -9x = 72 x = -8

Let x equal the second number. 9x equals the first number. Their product, 9x^2 = 17822.25 Solve for x x^2 = 1980.25 x = 44.5 9x = 400.5 Check it. 400.5 x 44.5 = 17822.25 It checks.
