Which of the following shows 12⁄28 written in prime factored form to in reducing the fraction to simplest form? a. 3⁄7 b. 6×2 ⁄7×4 c. 7×2×2⁄3×2×2 d. 3×2×2⁄7×2×2

Step-by-step explanation:

we need to find the options in prime factored form to help in reducing the fraction to simplest form

prime factors for 12 is 2 times 2 times 3

prime factors for 28 is 2 times 2 times 7

LEts replace all the factor in the fraction

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
