Answer:
54 or 15
Step-by-step explanation:
x = any number
x = 3
First solve the brackets:
2x + 3
(2x3) + 3 = 9
2x = 6
I can help you up to here because the question isn't worded properly.
If you are multiplying then it would be: 9x6 = 54
If you are adding then: 9+6 = 15
Hope this helps!
Y^2-5=31 add 5 to both sides
y^2=36 take the square root of both sides..
y=±√36
y=±6
y=-6 and 6 so B and D is the answer.
3/8 = 0,375
5/12 = 0,416
5/12 is bigger
Answer:
$7.08
Step-by-step explanation:
59 cents = 1 sq ft
? = 12 sq ft
To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.
0.59 * 12 = 7.08
Therefore, the cost of 12 sq ft is $7.08.
Please mark brainliest if possible and have a nice day.
Hello!
log₃(x) + log₃(x - 6) = log₃(7) <=>
<=> log₃(x * (x - 6)) = log₃(7) <=>
<=> log₃(x² - 6x) = log₃(7) <=>
<=> x² - 6x = 7 <=>
<=> x² - 6x - 7 = 0 <=>
<=> x² + x - 7x - 7 = 0 <=>
<=> x * (x + 1) - 7 * (x + 1) = 0 <=>
<=> (x + 1) * (x - 7) = 0 <=>
<=> x + 1 = 0 and x - 7 = 0 <=>
<=> x = -1 and x = 7, x ∈ { 6; +∞ } <=>
<=> x = 7
Good luck! :)
