Simplify the expression 5(1 + 3z)
A.
5 + 15z
B.
6 + 8z
C.
5 + 3z
C. 5 + 3z
wrong
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
24ab5c + 42a3b8
A.
8a^3b^13(3c + 5)
B.
6ab^5(4c + 7a^2b^3)
C.
6ab(4b^4c + 7a^2b^7)
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)
ur wrong
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).
Solve for x:
4(3x - 4) + 8 = 40
A.
13
B.
3
C.
4
D.
12
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.
