Answer:

16 Units.

Step-by-step explanation:

Given:

  • AC = 2 (x-3)
  • BD = x + 5

THIS CASE ⇒ AC = BD

⇒ Substitute the values

2 (x - 3) = x + 5

⇒ Clear the value of x

2x - 6 = x + 5

2x - x = 5 + 6

x = 11

⇒ Substitute the value of x in any of the equations

11 + 5 = 16

⇒ Length of each diagonal is 16 units.

Answer:

AC = 22

BD = 22

Step-by-step explanation:

The diagonals of a rectangle are equal in length.

⇒ AC = BD

⇒ 2(x - 4) = x + 7

⇒ 2x - 8 = x + 7

⇒ 2x - x = 7 + 8

⇒ x = 15

Substitute found value of x into the expressions for AC and BD:

AC = 2(x - 4)

     = 2(15 - 4)

     = 2(11)

     = 22

BD = x + 7

     = 15 + 7

     = 22

find the perimeter of an isosceles triangle with side lengths of 5+x, 5+x, and xy. Write in simplest form.
Zinaida [17]
<h3>Answer: perimeter = 10+2x+xy</h3>

To get the perimeter, you add up all the outer sides

side1+side2+side3 = (5+x)+(5+x)+(xy) = 10+2x+xy

The like terms 5 and 5 add to 10. The other pair of like terms x and x add to 2x. There isn't anything to pair with xy, so we leave it as is.
