Of the following two statements , which is a good definition ? Explain . " A rectangle is a parallelogram with 4 right angles . " " A rectangle is a parallelogram . " The first statement ; it is reversible . B. The first statement , a rectangle can either be a parallelogram , or it can have four right angles . The second statement all parallelograms are also rectangles . D. The second statement : a rectangle is always a parallelogram , but it may not have exactly four right angles .

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

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)
