Question

In rectangle ABCD, AC = 2x + 15 and
BD = 4x - 5. Find x.

Answer 1

Answer:

x=10

Step-by-step explanation:

In a rectangle,

AB=CD, BC=AD, AC=BD

Now, AC=BD

2x+15=4x-5

=> 4x-2x=15+5

=> 2x= 20

=> x=20/2

=> x=10

Answer 2

Answer:

x = 10

Step-by-step explanation:

AC = BD

4x - 5 = 2x + 15

2x = 20

x = 10
