8 x² + 64 x = 0
x · ( 8 x + 64 ) = 0
x = 0, or: 8 x + 64 = 0
8 x = - 64
x = - 64 : 8
x = - 8
Answer : x = 0, or x = -8

Which equation has the solution x = 3?

dybincka [34]

Answer:

2x + 4 = 10 = x =3

Step-by-step explanation:

09 - 31 = 0 (the variable x is not present in the given system)

0 +5=6 (the variable x is not present in the given system)

2x + 4 = 10 = x = 3

09-1=4 (the variable x is not present in the given system)

51 - 7 = 1 (the variable x is not present in the given system)

3x + 1 = 9 = x = 8/3

Braxton loves downloading new music he originally had 41 songs but plans to purchase 4 new songs each week. he wants to know how

ycow [4]

Answer:

$a_110=41+(110-1)4$

Step-by-step explanation:

He already has songs = 41

Since we are given that he purchase four songs every week .

So, in first week he purchase songs = 4

Initially he already has 41 songs

So, total songs after 1 week = $41+(4\times1)=45$

After 2 weeks he will have songs = $41+(4\times 2)=49$

This forms an arithmetic sequence : 41,45,49......

Formula of nth term in A.P. : $a_n=a+(n-1)d$

a = first term = 41

d = common difference = 45-41=49-45=4

Since we are required to find the new songs after110 weeks

So, n =110

Substituting values :

$a_110=41+(110-1)4$

Thus Option A is correct.
