Hello! :)

15 - 2x = 3x Simplify both sides of the equation

15 - 2x = 3x

-2x + 15 =3x

-2x + 15 - 3x = 3x -3x Subtract 3x from both sides

-5x + 15 = 0

-5x + 15 - 15 = 0 - 15 Subtract 15 from both sides

-5x = -15

- 5x/-5 = -15/-5

x = 3 (ANSWER)

Hope this helped you

Answer:

The surface area of door is 33 680 cm².

Step-by-step explanation:

Given that the surface area of a cuboid which is the 3D of rectangle is :

$s.a = 2(l \times w) + 2(l \times h) + 2(w \times h)$

$let \: l = 80 \\ let \: w = 3 \\ let \: h = 200$

$s.a = 2(80 \times 3) + 2(80 \times 200) + 2(3 \times 200)$

$s.a = 2(240) + 2(16000) + 2(600)$

$s.a = 480 + 32000 + 1200$

$s.a = 33680 \: {cm}^{2}$

boyakko [2]

4y ≥ 3x + 2

Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20
