speed = Distance ÷ time
Step-by-step explanation:
S = 8km ÷ 0.5h
S = 16km/h
Front yard
65+65+45+45=220
Back yard
45+45+35+35=160
220+160=380
380 feet
-0.1 - (x) = 0.3
-0.1 - (-0.4) = 0.3
-0.1 + 0.4 = 0.3
0.3 = 0.3 (true)
-0.4 is your answer

The number of positive integers n, that satisfy 3^n+81 the square of an integer is infinite.
<h3>How to illustrate the information?</h3>
Based on the information given, let 3n + 82 = p².
Therefore, 3n = p² - 81
= (p - 9)(p + 9)
Let p = 3q.
3n = (3q - 9)(3q + 9(
= 9(q - 3)(q + 4)
n = 3(q - 3)(q + 3)
n > 0 ; q >= 4 for n = 4, 5, 6....
