2 • (3 + 3d)

Answer 1

To simplify the expression $2\cdot (3+3d)$, you can distribute the 2:

$$2\cdot (3+3d)=2\cdot 3+2\cdot 3d=6+6d$$

So, the simplified expression is:

$$6+6d$$

Answer 2

2 • (2 + 3d)

Answer 3

To simplify the expression $2\cdot (2+3d)$, you can distribute the 2:

$$2\cdot (2+3d)=2\cdot 2+2\cdot 3d=4+6d$$

So, the simplified expression is:

$$4+6d$$

Answer 4

4 (5 + 4d)

Answer 5

To simplify the expression $4\cdot (5+4d)$, you can distribute the 4:

$$4\cdot (5+4d)=4\cdot 5+4\cdot 4d=20+16d$$

So, the simplified expression is:

$$20+16d$$

Answer 6

2 • 3/2

Answer 7

To calculate $2\cdot \frac{3}{2}$, you can multiply the whole number by the fraction:

$$2\cdot \frac{3}{2}=\frac{2\cdot 3}{2}=\frac{6}{2}=3$$

So, $2\cdot \frac{3}{2}=3$.

Answer 8

2 • (2 + 2m )

Answer 9

To simplify the expression $2\cdot (2+2m)$, you can distribute the 2:

$$2\cdot (2+2m)=2\cdot 2+2\cdot 2m=4+4m$$

So, the simplified expression is:

$$4+4m$$

Answer 10

3(5 + 2m)

Answer 11

To simplify the expression $3(5+2m)$, you can distribute the 3:

$$3(5+2m)=3\cdot 5+3\cdot 2m=15+6m$$

So, the simplified expression is:

$$15+6m$$
