A postcard in the shape of a parallelogram has an area of 12in^2. What are two possible lengths of bases and heights for the pos

Tpy6a [65]

A postcard is in the shape of a parallelogram. A parallelogram is a quadrilateral with two pair of parallel sides, opposite sides and opposite angles are equal.

Since, the postcard has an area of 12 square inches.

Since, area of parallelogram = $base \times height$

As area of parallelogram is 12, it means that the product of base and height is 12 square inches.

So, the possible dimensions of postcard are 3 inches and 4 inches and 2 inches and 6 inches.

So, base = 3 inches , height = 4 inches or base = 4 inches , height = 3 inches.

So, base = 2 inches, height = 6 inches or base = 6 inches , height = 2 inches.

Find the domain of the rational expression: x-3/2x-8

miss Akunina [59]

Answer:

$\huge\boxed{x\neq4\to x\in\mathbb{R}\backslash\{4\}}$

Step-by-step explanation:

$\dfrac{x-3}{2x-8}$

We know: the denominator must be different than 0.

Therefore

$2x-8\neq0$ <em>add 8 to both sides</em>

$2x-8+8\neq0+8$

$2x\neq8$ <em>divide both sides by 2</em>

$\dfrac{2x}{2}=\dfrac{8}{2}\\\\x\neq4$

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second

navik [9.2K]

Answer:

6m

Step-by-step explanation:

the side of first square = 3 m

area of first square = 3^2= 9 m^2

let the side of second square = x m

since diagonal of first square = x m as per the question

in a square each angle is 90 degree

therefore by applying pythagorus theorem ,

diagonal ^2 = side^2 + side ^2

diagonal^2 = 3^2+3^2=9+9

DIAGONAL= square root of 18

diagonal= 3 $\sqrt{2}$ m = side of second square

therefore in second square ,

one angle is 90 degree , therefore by applying pythagorue theorem

diaqonal^2 = side ^2 + side ^2 = (3 $\sqrt{2}$ )^2 + ( 3 $\sqrt{2}$ )^2

diagonal ^2 = 18 + 18

diagonal = square root of 36

therefore diagonal of second square is 6m

hope it helps you... please mark me as the brainliest..
