Write the expression as a single logarithm Log7X+log7Y-log7Z

For this, simply use the rules of logs:

- Adding logs of the same base (which is 7 here) is the same as multiplying

-Subtracting logs of the same base is dividing
 So the single log would be:

log₇(x*y/z) which is the same as

log₇(xy/z)

I will mark brainliest to whoever gets this answer! Please help!
lisov135 [29]

Answer:

20 yd²

Step-by-step explanation:

This problem is really easy once you break it down!

First, find the area of the triangle.

A = \frac{1}{2}bh

b = 5 + 3 = 8

h = 4 + 4 = 8

A = \frac{1}{2}*8*8

A = 32

Now find the area of the square.

A = lw

A = 4*3

A = 12

The last step is to subtract.

Area of triangle - area of rectangle =

32 - 12 = 20

20 yd²

Hope this helped! :)

Can you please help me with number 4. 15 points and if you don't know the answer don't say anything please.

You know the product will be greater than the two factors because multiplication always makes the numbers greater. So 2x12 is 24 and that is greater than the two factors
