Answer:

  x = 3

Step-by-step explanation:

Expand the left side and solve the resulting 2-step linear equation.

  x^2 -(4 -4x +x^2) = 8

  x^2 -4 +4x -x^2 = 8 . . . . . eliminate parentheses

  -4 +4x = 8 . . . . . . . . . . . . . collect terms

  -1 +x = 2 . . . . . . divide by 4

  x = 3 . . . . . . . . . add 1

35% = 0.35
500 x 0.35 = 175
500 + 175 = 675 per month
675 x (12 x 3) = $24,300 sales over three years (I’m not sure what answer is wanted for this question)

What is it a ,b,c,or D can I get a step by step explanation
ANEK [815]
The answers are b and c. Plug in -4 for x and solve each option

2(-4) -8 = 0. 0 does not equal 1
3(-4) +8 = -4
1/2 * -4 + 3 = 1, -4+5 = 1
2(1- -4) = 10, -4 + 2 = -2

Prove 2/sqrt3cosx+sinx=sec(pi/6-x)
dlinn [17]

Thus L.H.S = R.H.S that is 2/√3cosx + sinx  = sec(Π/6-x) is proved

We have to prove that

2/√3cosx + sinx  = sec(Π/6-x)

To prove this we will solve the right-hand side of the equation which is

R.H.S = sec(Π/6-x)

          = 1/cos(Π/6-x)

[As secƟ = 1/cosƟ)

           = 1/[cos Π/6cosx + sin Π/6sinx]

[As cos (X-Y) = cosXcosY + sinXsinY , which is a trigonometry identity where X = Π/6 and Y = x]

           = 1/[√3/2cosx + 1/2sinx]

            = 1/(√3cosx + sinx]/2

            = 2/√3cosx + sinx

    R.H.S = L.H.S

Hence 2/√3cosx + sinx  = sec(Π/6-x) is proved
