Answer:log₂(
)
Explanation:Before we begin, remember the following:logₐ(x) - logₐ(y) = logₐ(
)
alog(x) = log(xᵃ)
Now, for the given we have:3 log₂(x) - (log₂3 - log₂(x+4))
log₂(x²) - log₂(
)
log₂(
) = log₂(
)
Hope this helps :)
A9x) = x^2 - 6x + 9 = (x - 3)^2

Answer:
Step-by-step explanation:
The price difference is found by subtracting Emma's price from DeShawn's price. Each price is the product of the number of square feet and the price per square foot.
The number of square feet is already given in the answer form, so you only need to fill in the per square foot prices. Those are found in the table. Both the window name and the window area give clues as to which is the right price to choose.
The expression is (4² × 33) - (3² × 27).
__
For the second fill-in, you need to actually do this arithmetic. For many calculators, you can enter this expression directly.
DeShawn paid $285 more for his window than Emma.
Answer:
Yes, B
Step-by-step explanation:
Yes the data is linear because there is a constant rate of change.
For x or the input the rate of change is plus 2
For y or the output the rate of change is plus 4
y/x is your slope so 4/2=2
and the only equation with a slope of 2 is B
Answer:
15=2x
There are fifteen 1 blocks and two x blocks, which makes 15=2x(or 2x=15)
