You're working on
Distributive Property (A) — a foundational algebra skill. The distributive property says:
>
a(b + c) = ab + ac
> or more generally,
>
a(b ± c) = ab ± ac
This means you multiply the term *outside* the parentheses by *each term inside* the parentheses, and then combine like terms if needed.

Let’s solve each expression one by one, applying the distributive property carefully.

Left Column:
1. 2(4 + 9w)
= 2×4 + 2×9w
=
8 + 18w
2. -4(-4d - 5)
= (-4)×(-4d) + (-4)×(-5)
=
16d + 20
3. 2(3v - 8)
= 2×3v - 2×8
=
6v - 16
4. 4(-6z + 4)
= 4×(-6z) + 4×4
=
-24z + 16
5. (-5d + 1)(-2)
= (-2)×(-5d) + (-2)×1
=
10d - 2
6. 2(-5 - 7j)
= 2×(-5) + 2×(-7j)
=
-10 - 14j
7. -3(3 - 8j)
= (-3)×3 + (-3)×(-8j)
=
-9 + 24j
8. -8(2 + 9v)
= (-8)×2 + (-8)×9v
=
-16 - 72v
9. (-5f + 8)4
= 4×(-5f) + 4×8
=
-20f + 32
10. -(6 - 4p)
This is the same as
-1(6 - 4p)
= (-1)×6 + (-1)×(-4p)
=
-6 + 4p or
4p - 6
---
Right Column:
1. -8(6x + 3)
= (-8)×6x + (-8)×3
=
-48x - 24
2. -6(8p + 3)
= (-6)×8p + (-6)×3
=
-48p - 18
3. (2 - 5m)(-5)
= (-5)×2 + (-5)×(-5m)
=
-10 + 25m
4. -9(n - 4)
= (-9)×n + (-9)×(-4)
=
-9n + 36
5. -4(9k + 9)
= (-4)×9k + (-4)×9
=
-36k - 36
6. (3b - 2)(-3)
= (-3)×3b + (-3)×(-2)
=
-9b + 6
7. -(-5 - 3v)
This is
-1(-5 - 3v)
= (-1)×(-5) + (-1)×(-3v)
=
5 + 3v
8. -9(8 - 2h)
= (-9)×8 + (-9)×(-2h)
=
-72 + 18h
9. (7x - 8)(-1)
= (-1)×7x + (-1)×(-8)
=
-7x + 8
10. 9(8 + 5t)
= 9×8 + 9×5t
=
72 + 45t

Tip: Always watch your signs! Multiplying two negatives gives a positive. A negative times a positive gives a negative.
