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
Answer:
y = x - 10
Step-by-step explanation:
10 less than a number is the same as 10 subtracted from the number.
If you start with 30, 10 less than 30 is the same as 10 subtracted from 30.
30 - 10 = 20. The input is 30, and the output is 20, which is 10 less than 30.
If you start with x, 10 less than x is the same as 10 subtracted from x, or x - 10. The input is x. Subtract 10 from the input, or x - 10. The output equals x - 10.
y = x - 10
Answer:
z = 4
Step-by-step explanation:
12z - 18 = 30
add 18 to both sides:
12z = 48
divide by 12:
z = 4
The answer is C for that question
