Nine times the sum of a number and 2 is 189. I need to make it to an equation.
Olegator [25]

<em>Equation:</em>

9(a+2)=189

<em>Solve the equation:</em>

9a+18=189

9a=189-18

9a=171

a=171/9

a=19

<em>Check the solution:</em>

Let a=19

9(a+2)=189

9(19+2)=189

171+18=189

189=189


Therefore, the equation is 9(a+2)=189 and a is 19.

How do I factor the following expression?
Crazy boy [7]

\bf x^6-9x^4-81x^2+729\implies \stackrel{\textit{let's do some grouping}}{(x^6-9x^4)-(81x^2-729)} \\\\\\ \stackrel{\textit{some common factoring}}{x^4\boxed{(x^2-9)}-81\boxed{(x^2-9)}}\implies \stackrel{\textit{common factoring}}{\boxed{(x^2-9)}(x^4-81)} \\\\\\ \stackrel{\textit{difference of squares}}{[x^2-3^2][(x^2)^2-(3^2)^2]}\implies (x-3)(x+3)\stackrel{\textit{difference of squares}}{(x^2-3^2)}(x^2+3^2) \\\\\\ (x-3)(x+3)~(x-3)(x+3)~(x^2+9)

Find the area of each shaded segment in nearest tenth.
shepuryov [24]

Answer:

Denote the center of circle as O, the 2 endpoints of shaded segment as AB, then we have:

section OAB area = pi x radius^2 x (120/360) = pi x 6^2 x (1/3) = 37.7 (cm2)

Considering triangle OAB, we have OA = OB = radius, angle AOB = 120 deg. Denote OH as the height of triangle. H lies on AB.

=> Applying cosine and sine theorem in right triangle AHO:

OH = OA x cos 60 = 6 x (1/2) = 3 (cm)

AH = OA x sin 60 = 6 x (sqrt3)/2 = 5.2 (cm)

=> triangle AOB area:

A = triangle AOH area x 2

   = AH x OH x (1/2) x 2 = 3 x 5.2 x (1/2) x 2 = 15.6 (cm2)

=> shaded segment area = section OAB area - triangle AOB

                                          = 37.7 - 15.6 = ~21.1 (cm2)

Hope this helps!
