Answer:
i dont know it (sad face)
Step-by-step explanation:
X^2 + yz......x = 5, y = -3, z = 2
now we sub
5^2 + (-3)(2) =
25 + (-6) =
25 - 6 =
19
Solving inequalities is just like solving any other Algebraic problem...look to P.E.M.D.A.S. (Parenthesis, Exponents, Division, Addition, Subtraction). So lets take a look at this problem now.
1200 + 0.075x

3300
Subtract 1200 from both sides...
0.075x

2100
Now divide by 0.075...
x

28000
NOTE: If you divide or multiple by a negative number while solving inequalities, you must flip the sign. Ex: You answer would be x

28000 if you would've multiplied or divided by a negative.
To do this, you got to square 256.
The square root of 256 is 16.
Therefore, there are 16 small squares on each edge of the mosaic.
Kinda proof:
o o o o O
o o o o O
o o o o O
o o o o O
o o o o O
25 squares. Square root is 5. 5 along each edge. My work shares same concept.
Extremely unnecessary proof:
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
There are 256 squares, and you can count 16 on each edge. this shows 16 times 16, or 16 squared, which is 256.
The mean is 2.5. also there is mean, median, mode calculators online to help you with these in the future
