Lourdes is making a frame in the shape of a parallelogram. She adds diagonal braces to strengthen the frame. Parallelogram A B C

zimovet [89]

Answer:

60 cm

Step-by-step explanation:

Parallelogram ABCD is shown in attached diagram. The diagonals of the parallelogram bisect each other, so

AE = EC

BE = ED

Ib DE = 3y + 6 cm, BE = 5y - 10 cm, then

$3y+6=5y-10\\ \\3y-5y=-10-6\\ \\-2y=-16\\ \\2y=16\\ \\y=8\ cm$

Now, EC = 2y + 4, so

$EC=2\cdot 8+4=16+4=20\ cm$

Since AE = EC, then AE = 20 cm

The brace that connects points B and D has the length

$BD=BE+ED=3y+6+5y-10=8y-4=8\cdot 8-4=64-4=60\ cm$

The brace that connects points A and C has the length

$AC=AE+EC=20+20=40\ cm$

They get ten times smaller, so you could say a number is getting divided by ten or the decimal point is moving to the left one place value.
