Snowcat [4.5K]

1st gift shop:

120/4 = 30 cents each

180/6 = 30 cents each

390/13 = 30 cents each

 

2nd gift shop:

204/7 = 29.14 cents each

192/8 = 24 cents each

270 /9 = 30 cents each

360/10 = 36 cents each

Multiply.<br> (5x2-6x+2) x (4x2-3x)
stich3 [128]

Answer:

<em>18x² - 84x + 96</em>

Step-by-step explanation:

(5 × 2 - 6x + 2) × (4 × 2 - 3x)

5 × 2 (4 × 2 - 3x) - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 48x + 18x² - 6x

96 - 84x + 18x²

18x² - 84x + 96

Hope this helps! :)

Sladkaya [172]
If we have 156 beads and we can make one bracelet with 9 beads we divide 156 by 9 and get 17 1/3. since we cannot have 1/3 of a bracelet, we can make 17 bracelets.
