the perimeter of the rectangle below is 98 units. Find the length of CD. Write your answer without variables. cd=4x+3 cb=5x+1

zimovet [89]

$2(4x + 3) + 2(5x + 1) = 98 \\ 8x + 6 + 10x + 2 = 98 \\ 18x + 8 = 98 \\ 18x = 90 \\ x = 5$
Substitute x with 5,

CD =
$4x + 3 \\ = 4(5) + 3 \\ = 20 + 3 \\ = 23$
CD = 23 units

Hope this helps.
