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! :)
5 square units let me know if it’s correct hun
Answer: $3.60
Explanation:
2.40 ÷ 8 = 0.3 (3 cents per slice)
0.3 x 12 = 3.60
Answer
80
Step-by-step explanation:
1/5 of 120 is 24
120 - 24 because you dropped 1 /5
gives you 96
then you give 1/6 of what you have left to your friend and that means giving 16 candies to your friend so 96-16
and that gives you 80 candies remaining
answer:
21 + 3x (you would not put the x again since it is already given)
step-by-step explanation:
- we have to distribute 3 to the expression in the parenthesis
3 (7 + x)
= 21 + 3x
- this will be the expression once we distribute
