Multiply the numbers and simplify the answers 3× 1 3/4

Hello from MrBillDoesMath!

5 1/4

Discussion:

1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4

So the product

3 * 1 3/4 =

3 * (7/4) =

21/4 =

5 1/4

Thank you,

MrB

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)
