Answer:
x = 2.5
Step-by-step explanation:
4( x + 7) = 38
step 1 distribute the 4 to the x and 7
4 * x = 4x
4 * 7 = 28
we now have 4x + 28 = 38
step 2 subtract 28 from each side
28 - 28 cancels out
38 - 28 = 10
we now have 4x = 10
step 3 divide each side by 4
4x / 4 = x
10 / 4 = 2.5
we're left with x = 2.5

Step-by-step explanation:
Answer:
2^(1 + ((n-1) mod 4)) mod 10
Step-by-step explanation:
We presume you want the last digit of the power of 2, not the last digit of the exponent. Powers of 2 mod 10 are ...
2^0 : 1
2^1 : 2
2^2 : 4
2^3 : 8
2^4 : 6
2^5 : 2 . . . . and the sequence repeats: 2, 4, 8, 6, ...
That is, ...
(2^n) mod 10 = 2^(1 + ((n-1) mod 4)) mod 10 . . . for n > 0
