<h3><u>Answer:</u></h3>

\boxed{\pink{\sf\leadsto Value \ of \ x \ is \ 24^{\circ}}}

<h3><u>Step-by-step explanation:</u></h3>

In the given parallelogram we can see that , <B is 5x° and <C is equal to 2x + 12°.

And these two are co - interior angles . And sum of co - interior angles is 180°.

Hence , here

\tt:\implies \angle DCB + \angle ABC = 180^{\circ} \\\\\tt:\implies (2x + 12)^{\circ} + 5x^{\circ}=180^{\circ} \\\\\tt:\implies 7x = (180 - 12 )^{\circ} \\\\\tt:\implies 7x = 168^{\circ} \\\\\tt:\implies x =\dfrac{168^{\circ}}{7} \\\\\underline{\boxed{\red{\tt\longmapsto x = 24^{\circ}}}}

<h3><u>Hence the value of x is 24°</u><u>.</u></h3>

"If a = − 9 and b = − 6, show that (a−b) ≠ (b−a)."
denis-greek [22]

Answer:

Step-by-step explanation:

LHS  a - b = -9 - (-6) = -9 +6 = -3

RHS  b-a = -6 - (- 9) =  -6 +9 = 3

as LHS not equal to RHS

a-b not equal to b-a

Thus proven

The cereal box has a volume of 432 in if the base has dimensions of 2 in by 12 in what is the height of the box
OlgaM077 [116]

Answer:

Height of the cereal box = 18 in.

Step-by-step explanation:

A cereal box is in the shape of a cuboid.

And volume of a cuboid is represented by the expression,

Volume = Length × Width × Height

It's  given that volume of the box = 432 in³

Length of the base = 2 in.

Width of the base = 12 in

By substituting these values in the expression,

432 = 2 × 12 × h

h = \frac{432}{24}

h = 18 in.

Therefore, height of the cereal box is 18 in.
