Mar 12, 2017 · √6x − 5+10 −10 = 3 −10 ⇒ √6x −5 = −7 square both sides (√6x − 5)2 = (− 7)2 ⇒ 6x − 5 = 49 add 5 to both sides. 6x−5 +5 = 49+ 5 ⇒ 6x = 54 divide both sides by 6 6x 6 = 54 6 ⇒ x = 9 As a …

Nov 19, 2016 · Explanation: After play with some of the pairs to combine #6, 24 and 30# #6x^2 - 24x - 30 = 0# can be factored to:

Let f (x)=6x^3-7x^2-9x-2 and substitute these values to x and you will find f (2)=0. This means that x=2 is one of the roots and thus f (x) is divisivle by (x-2).

f (x) has zeros +-sqrt (5) and -2 Given: f (x) = 3x^3+6x^2-15x-30 Note that all of the terms are divisible by 3. In addition, the ratio of the first and second terms is the same as that of the third and fourth terms.

Let "mass of X" = x and "mass of O" = y. y/ (x + y) = 0.6 y = 0.6x + 0.6y 0.4y = 0.6x y = (0.6x)/0.4 = 1.5x Let "mass of x = 32 u". Then "mass of O = 1.5 × 32 u = 48 u". ulbb ("Element"color (white) …

Jan 29, 2017 · 6x^2+x-1 = (2x+1) (3x-1) Here are a couple of methods (in no particular order): Method 1 Note that: (ax+1) (bx-1) = abx^2+ (b-a)x-1 Comparing with: 6x^2+x-1 we want to find a, b such that …

Measure of angle LhatOM = 48^0 7x-92+6x+12=180 1) Combine like terms 7x - 92 + 6x + 12 =180 13x - 80= 180 2) Add color (blue) (80) to both sides (13x) - cancel80 color (blue) (+ cancel80) = 180 color …

Using [1] 3y+6x=-24 3y=-24-6x color (blue) (y=-8-2xcolor (white) (888) [3] Substituting [3] in [2] z=-2 (-8-2x)-16 z=16+4x-16 z=4x Now find y in terms of x. This is equation [3] we found earlier.

0, 1, 3 To solve this, we set the equation equal to 0 and factor it. First, we can factor out 6x to get 6x(x^2-4x+3)=0. Next we can factor out the area in parentheses. To do this, we need to find two …
