Answer: 2. 9x.8y / 3.9,8,2
Hope it helps
Step-by-step explanation
Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units
Answer:
The temperature at the end of the day is 2 degrees
Step-by-step explanation:
Here, we are interested in calculating the temperature at the end of the day.
In the question, we are told that at the beginning of the day, temperature was -14 degrees.
But throughout the day, the temperature increased by 16 degrees;
Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees
