In the rectangle below AC has a length of 28. What is the length of ED? If necessary, round your answer to two decimals places.
expeople1 [14]
<span>The diagonals of a rectangle have equal lengths. Since AC has a length of 28, and AC is a diagonal, the other diagonal BD also has a length of 28. The diagonals of a rectangle also bisect each other. So diagonal BD is bisected by the other diagonal AC at point E. And since diagonal BD has a length of 28 then BE and ED both have a length which is of 28, or 14 each.

Answer: ED has a length of 14.</span>

Multiply the following polynomials
Sophie [7]

Answer  (2x + 7) • (x2 - 2)

Step-by-step explanation:

please give me brainlest!!

Step by step solution :

Step  1  :

Trying to factor as a Difference of Squares :

1.1      Factoring:  x2-2

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 2 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

 (2x + 7) • (x2 - 2)
