Answer: 2 to seventy second power . 5 to tenth power l hope this heIps :)
Step-by-step explanation:
Answer:
-1 and -2, or 9 and 10
Step-by-step explanation:
If x is the smaller integer:
x (x + 1) = 14 + 4 (x + x + 1)
x² + x = 14 + 4 (2x + 1)
x² + x = 14 + 8x + 4
x² − 7x − 18 = 0
Factor using AC method:
(x − 9) (x + 2) = 0
x = -2 or 9
x is the smaller integer, so the larger integers are -1 and 10. Check each pair of solutions.
-1 and -2:
(-2) (-1) = 14 + 4 (-2 + -1)
2 = 14 + 4 (-3)
2 = 2
9 and 10:
(9) (10) = 14 + 4 (9 + 10)
90 = 14 + 4 (19)
90 = 90
Both solutions work.
Answer: 
Step-by-step explanation:
<h3>
The exercise is: "To visit his grandmother, Michael takes a motorcycle 3.85 kilometers and a horse 3.32 kilometers. In total, the journey takes 50.54 minutes. How many kilometers is Michael's journey in total?"</h3>

According to the information provided in the exercise, Michael's journey is divided into two parts:
Part 1:
(Traveling in a motorcycle)
Part 2:
(Traveling in a horse)
Based on the given data, you can conclude that the the total distance in kilometers of Michael's journey to the house to his grandamother, is the sum of those distances (
and
)
Therefore, you need to add them in order to solve the exercise.
So, You get that the result is:
The answer is 10i.
