Answer:
w = 5
Step-by-step explanation:
-27 + 20w = 73
add 27 to both sides
-27 + 27 + 20w = 73 + 27
20w = 100
divide both sides by 20
20w/20 = 100/20
w = 5
Answer:
12
Step-by-step explanation:
To find the mean, we add up all the numbers and divide by the number of numbers
(19+ 12+9+ 6+ 12+ 8+ 18+ 12+ 14+ 10)/10
120/10
12
Difference of 2 perfec squares is
(a^2)-(b^2)
if the exponents are both even and the coeficient (the number in front) are perfect squares, then it is difference t 2 perfect squares
first one
8 is not perfect square
2nd one
(4e^4)^2-(9g^2)^2
third
25 is odd, so it cannot be split up into 2 nice numbers
4th
(11m^9)^2-(3n^5)^2
The answer to your question would be 6!
