Answer:
ln 27x²
Step-by-step explanation:
Using the rules of logarithms
• log
⇔ nlogx
• logx + logy ⇒ logxy
Given
3 ln 3 + 2 ln x, then
= ln 3³ + lnx²
= ln 27 + lnx² = ln 27x²
10 because she already knows 3 so then you divide 80 (number of words she hasn’t learned) by 8 (the number of weeks) and you get 10.
Answer:
my bad it was a mistake .
Step-by-step explanation:
For how many books he got : 4
This is but adding up 3 of $3.95 to get the total of $11.85
You then want to subtract that from $47.65 to get $34.80
You subtract that by the $8.95 4 times so you see he bought 4 books
After you talk about how many books did he buy after that sentence I’m not sure what your saying
Answer:
8 x 4
Step-by-step explanation:
Lets say the length is x and the width is y.
xy = 32
2x + 2y = 24
Rearranging the second equation, we get:
2x = 24 - 2y
/2 /2
x = 12 - y
substitute into the first equation
y(12 - y) = 32
12y - y^2 = 32
-32 -32
-y^2 +12y - 32 = 0
x -1 x -1
y^2 - 12y + 32 = 0
(y - 8)(y - 4) = 0
y = 8 or 4
substitute into x = 12 - y.
x = 12 - 8 = 4
x = 12 -4 = 8
so the correct dimensions are 4 x 8, as either x = 4 and y =8, or x = 8 and y = 4.
Hope I helped!
