Which step gives an incorrect property or reason in the process of solving the equation? -4(3x+6) +6=-30

-12x-12+6=-30 by the distributive property (Step 1)

-12x -6=-30 by the Commutative Property (Step 2)

-12x -6+6 = -30 +6 Addition (Step 3)

-12x +0 = -24 Additive inverse & Substitution (Step 4)

-12x = -24 Additive Identity (Step 5)

x = 2 Division (Step 6)

a

e
Step 5
f
Step 6

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

correct answer:

b.(19,-2)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
