Answer:

1. C. 4x + 40

2. a. - 2a + 10

3. d. 13x - 45

4. 2c-7d

5. b. -2z - 12

Step-by-step explanation:

1.  4(x+10)  = 4x+4*10 = 4x+40

C


2.  -2(a - 5) = -2*a -2*-5 = -2a+10

A


3.  10x + 3 (x-15)

10x + 3x -3*15

10x+3x-45

13x-45

D


4. -5(c+d) + 7c - 2d

-5c-5d + 7c-2d

-5c+7c -5d -2d

2c-7d


5.  2(2z + 4) - 2 (3z + 10)

2*2z +2*4 -2 *3z -2*10

4z+8 -6z-20

4z-6z+8-20

-2z-12

B
