2X - 3 = 18X -2X -2X ( Subtract 2X from both sides ) ------------------ -3 = 16X ( Divide both sides by 16 ) -------------------- so, X = -3/16 OR -.1875

How do you divide the following expression. Assume that the denominator is nonzero. 18x9 -12x7 -8x6 -2x3 all divided by -2x2?

In dividing (18x⁹ -12x⁷ -8x⁶ -2x³) ÷ -2x² you could do long division, but as the divisor contains a single term like a normal fraction each term of the dividend can be divided by the divisor and summed together: (18x⁹ -12x⁷ -8x⁶ -2x³) ÷ -2x² = (18x⁹ -12x⁷ -8x⁶ -2x³)/(-2x²) = 18x⁹/(-2x²) + -12x⁷/(-2x²) + -8x⁶/(-2x²) + -2x³/(-2x²) = (18 ÷ -2)(x⁹ ÷ x²) + (-12 ÷ -2)(x⁷ ÷ x²) + (-8 ÷ -2)(x⁶ ÷ x²) + (-2 ÷ -2)(x³ ÷ x²) = -9x⁹⁻² + 6x⁷⁻² + 4x⁶⁻² + 1x³⁻² = -9x⁷ + 6x⁵ + 4x⁴ + x

What is 3(6x) x?

To simplify the expression (3(6x) \times x), first calculate (3 \times 6x), which equals (18x). Then, multiply this result by (x): (18x \times x = 18x^2). Therefore, the simplified expression is (18x^2).


What is the x intercept of 18x plus 12y equals 72?

18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.

What is does x equal when the altitude of a triangle equals x plus 9 and the hypotenuse equals 26?

For this, you need the Pythagorean theorem. Let A equal x + 9 Let C equal 26 A^2 + B^2 = C^2 (x + 9)^2 + B^2 = 26^2 x^2 + 18x + 81 + B^2 = 676 x^2 + 18x + B^2 = 595 This doesn't help you find x, but I hope this did something!
