Answer:
The brownies will be a little thicker in a 9 x 13” pan. 8 x 8= 64 square inches, doubled that's 128. 9 x 13= 117
Step-by-step explanation:
The final elevation from sea level of the first climber is the difference of the elevation of the peak and the number of feet he descended to meet his fellow climber,
e = 14,090 ft - 490 ft
e = 13,600 ft
Thus, the answer is letter C. 13,600 ft.
Rule: The sum of any integer and its opposite is equal to zero. Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
The answer would be the first one, 2s+6.
From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
