Question

A.

5 + 15z
B.

6 + 8z
C.

5 + 3z

Answer 1

C. 5 + 3z

Answer 2

wrong

Answer 3

Apologies for the mistake, let's solve it correctly.

5(1 + 3z) = 5 + 5(3z)
5(1 + 3z) = 5 + 15z

Therefore, the correct answer is A. 5 + 15z

Answer 4

24ab5c + 42a3b8

A.

8a^3b^13(3c + 5)
B.

6ab^5(4c + 7a^2b^3)
C.

6ab(4b^4c + 7a^2b^7)

Answer 5

To simplify the expression 24ab5c + 42a3b8:

24ab5c + 42a3b8
= 6ab(4b^4c + 7a^2b^7) [Taking out common factors from both terms]

Therefore, the answer is C. 6ab(4b^4c + 7a^2b^7)

Answer 6

ur wrong

Answer 7

Let's correct that:

24ab5c + 42a3b8
= 24ab5c + 336a4b9
= 24ab(5c + 14a3b5)

The simplified expression is 24ab(5c + 14a3b5).

Therefore, the correct answer is: A. 24ab(5c + 14a3b5).

Answer 8

Solve for x:

4(3x - 4) + 8 = 40

A.

13
B.

3
C.

4
D.

12

Answer 9

To solve for x in the equation 4(3x - 4) + 8 = 40, we will apply the distributive property and then solve for x step by step:

4(3x - 4) + 8 = 40
12x - 16 + 8 = 40
12x - 8 = 40
12x = 48
x = 48 / 12
x = 4

Therefore, the correct answer is:

C. x = 4.

Answer 10

Identify the solution to 4(2x – 1) = 7 + 3x – 1.

A.

2
B.

⅖
C.

3
D.

10/3

Answer 11

To solve the equation 4(2x – 1) = 7 + 3x – 1, we will apply the distributive property and then solve for x step by step:

4(2x – 1) = 7 + 3x – 1
8x - 4 = 7 + 3x - 1
8x - 4 = 6 + 3x
8x - 3x = 6 + 4
5x = 10
x = 10 / 5
x = 2

Therefore, the correct answer is:

A. x = 2.
