Expand the following:
a).
$8(x - 2y)$
b).
$\frac{6a + 18b - 12c}{6}$
​

Answer 1

Answer:

8x-16y

Step-by-step explanation:

• b.6a/6+18b/6-12c/6

Answer 2

Answer:

8x - 16y and a + 3b - 2c

Step-by-step explanation:

(a)

8(x - 2y) ← multiply each term in the parenthesis by 8

= 8x - 16y

(b)

$\frac{6a+18b-12c}{6}$ ← factor out 6 from each term in the numerator

= $\frac{6(a+3b-2c)}{6}$ ← cancel the 6 on numerator/ denominator

= a + 3b - 2c
