Question

1) 10а + (4-4а); 3) (с - 5d) - (-d + 5с); 2) -(4b-10) + (4-5b);

Answer 1

Ответ:

1) 2(3a+2)

2) -9b + 14

3) -4 (c+d)

Answer 2

Ответ:

1. 6а+4

2. -9b-6

3. -4d-4c

Пошаговое объяснение:

1. 10а + (4-4а) = 10а + 4 - 4а = 6а + 4

2. -(4b-10) + (4-5b) = -4b - 10 +4 -5b = -9b -6

3. (с - 5d) - (-d + 5с) = c -5d +d -5c = -4d -4c

Answer 3

It looks like you've provided three mathematical expressions. If you'd like, I can help you simplify or solve them. Let's work through each expression:

1. 10a + (4 - 4a) = 10a + 4 - 4a (Distribute the negative sign) = 10a - 4a + 4 (Combine like terms) = 6a + 4 (Combine coefficients)

So, the simplified form is 6a + 4.

2. -(4b - 10) + (4 - 5b) = -4b + 10 + 4 - 5b (Distribute the negative sign and addition) = -9b + 14 (Combine like terms)

So, the simplified form is -9b + 14.

3. (c - 5d) - (-d + 5c) = c - 5d + d - 5c (Distribute the negative sign) = c - 5c - 5d + d (Reorder terms) = -4c - 4d (Combine like terms)

So, the simplified form is -4c - 4d.
