Given:

length of rectangle = 4 units

Height of rectangle = 2x + 6 units

To find:

Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.

Steps:

Perimeter of rectangle = 2(L + B)

= 2( 4 + 2x + 6 )

= 2( 10 + 2x )

= 2 * 10 + 2 * 2x

= 20 + 4x units

Area of rectangle = L * B

= 4 * (2x + 6)

= 4 * 2x + 4 * 6

= 8x + 24 units²

Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².

Happy to help :)

If you need any help, feel free to ask.

Answer:

The trigonometric equation (sin Θ − cos Θ)^2 − (sin Θ + cos Θ)^3 can be simplified by:Using x for Θ: (sinx - cosx)^2 - (sinx + cosx)^2 = (sin^2 x - 2sinxcosx + cos^2 x) - (sin^2 x + 2sinxcosx + cos^2 x) = - 2 sinx cosx - 2 sinx cosx = - 4 sinx cosx = - 2sin(2x)

Jorge solves the equation 4 x minus (x + 2) + 6 = 2 (3 x + 8) using the steps below. Step 1: 4 x minus x + 2 + 6 = 6 x + 16 Step

Answer:

The solution of the given equation is x = -4

Step-by-step explanation:

Explanation:-

Given expression 4 x - (x +2) +6 = 2 (3 x+8)

Step(i):-

4 x - (x +2) +6 = 2 (3 x+8)

4 x - x -2 + 6 = 6 x + 16

step(ii):-

3 x + 4 = 6 x + 16

subtracting '4' on both sides , we get

3 x + 4 - 4 = 6 x + 16 - 4

3 x = 6 x + 12

Step(iii):-

Subtracting '6x' on both sides , we get

3 x - 6 x = 6 x - 6 x + 12

- 3 x = 12

Step(iv):-

Dividing '-3' on both sides , we get

$\frac{-3x}{-3} = \frac{12}{-3}$

x = - 4

Final answer:-

The solution of the given equation is x = -4

Verification:-

4 x - (x +2) +6 = 2 (3 x+8)

put x = -4

4 ( -4) - ( - 4 +2) +6 = 2 (3(-4)+8)

-16+2+6 = 2 (-12+8)

-8 = -8

Both are equal
