Expand 4(3z − 7) .

4(3z − 7) can be expanded by distributing the 4 to each term inside the parentheses:

4(3z) − 4(7)

Simplifying further:

12z − 28

show me how to do that

To expand 4(3z - 7), you distribute the 4 to each term inside the parentheses:

First, distribute the 4 to the first term, 3z, in the parentheses:

4 * 3z = 12z

Next, distribute the 4 to the second term, -7, in the parentheses:

4 * -7 = -28

Finally, combine the terms to get the expanded form:

12z - 28

So, the expanded form of 4(3z - 7) is 12z - 28.

Expand −5(2q + 8) .(1 point)

To expand -5(2q + 8), you distribute the -5 to each term inside the parentheses:

First, distribute the -5 to the first term, 2q, in the parentheses:

-5 * 2q = -10q

Next, distribute the -5 to the second term, 8, in the parentheses:

-5 * 8 = -40

Finally, combine the terms to get the expanded form:

-10q - 40

So, the expanded form of -5(2q + 8) is -10q - 40.

Expand 710(5d+6) .

To expand 710(5d + 6), you distribute the 710 to each term inside the parentheses:

First, distribute the 710 to the first term, 5d, in the parentheses:

710 * 5d = 3550d

Next, distribute the 710 to the second term, 6, in the parentheses:

710 * 6 = 4260

Finally, combine the terms to get the expanded form:

3550d + 4260

So, the expanded form of 710(5d + 6) is 3550d + 4260.

Expand 7/10(5d+6) .

To expand 7/10(5d + 6), you distribute the 7/10 to each term inside the parentheses:

First, distribute 7/10 to the first term, 5d, in the parentheses:

(7/10) * 5d = (35/10)d = 3.5d

Next, distribute 7/10 to the second term, 6, in the parentheses:

(7/10) * 6 = (42/10) = 4.2

Finally, combine the terms to get the expanded form:

3.5d + 4.2

So, the expanded form of 7/10(5d + 6) is 3.5d + 4.2.
