We are given

Nancy bought an extra-large bag of 1,288 beads to make necklaces

When she got home, she found another bag with 784 beads in it

so, total number of beads =1288+784

total number of beads =2072

now, we have

For one necklace , 56 beads are required

so, 56 beads = 1 necklace

$1 bead=\frac{1}{56}necklace$

for 2072 beads

$2072*1 beads=2072*\frac{1}{56}necklace$

$2072 beads=37necklace$

so,

number of necklaces she can make is 37..........Answer
