Answer:

x=9

Let's solve your equation step-by-step

12(x−2)+3x=x+12+10x

<em>Step 1: Simplify both sides of the equation.</em>

12(x−2)+3x=x+12+10x

(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)

12x+−24+3x=x+12+10x

(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)

15x+−24=11x+12

15x−24=11x+12

<em>Step 2: Subtract 11x from both sides.</em>

15x−24−11x=11x+12−11x

4x−24=12

<em>Step 3: Add 24 to both sides.</em>

4x−24+24=12+24

4x=36

<em>Step 4: Divide both sides by 4.</em>

4x/4=36/4

x=9

Answer: x = 9

Step-by-step explanation:

12(x − 2) + 3x = x + 12 + 10x

12(x - 2) + 3x = 11x + 12

12x - 24 + 3x = 11x + 12

15x - 24 = 11x + 12

15x = 11x + 12 + 24

15x = 11x + 36

15x - 11x = 36

4x = 36

x = 36/4

<u><em>x = 9</em></u>

What is the perimeter of parallelogram HIJK? Round to the nearest hundredth.
bixtya [17]

Answer:

Perimeter of the parallelogram = 26.64 units

Step-by-step explanation:

The perimeter of parallelogram = 2(a + b)

Here a = KJ = 7 units.

b = HK

We need to find the HK using the distance formula.

Distance formula = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

H = (-4, 3) and k = (-2, -3)

Now plug in x1 = -4, y1 =3, x2 = -2, y2 = -3 in the distance formula

HK = \sqrt{(-2 -(-4))^2 + (-3 - 3)^2}

= \sqrt{(-2 +4)^2 + (-6)^2}

= \sqrt{4 + 36}

= \sqrt{40}

HK = b = 6.32 units

Now plug in a = 7 and b = 6.32 in the perimeter formula, we get

Perimeter = 2(7 + 6.32)

= 2(13.32)

= 26.64 units

Thank you.
