Answer:
the top one and bottom one
Step-by-step explanation:
2^2 = 4
just think 2 written out TWO times (hence the SECOND power).
Answer:
14,16
Step-by-step explanation:
Let x be the first even number.
Let y be the 2nd even number.
Given, y - x = 2 (Since they are 2 consecutive even numbers.)
rearranging the equation: y = x+2 (equation 1)
Also given,
(equation 2)
Now we can substitute equation 1 into equation 2 to find x.

Given the smaller even number x, is 14, we will substitute x into equation1 to find y, the bigger even number.
y = 14+2
= 16
Therefore the 2 numbers are 14 and 16.
Answer:
f = 100 + 0.133d
Step-by-step explanation:
For each trip, they charge an initial fee of 100 in addition to a constant fee for each vertical meter climbed.
For example, for 3000 meters of climbing, they charged the additional constant fee of 400.
Therefore, per meter climbing they charges
.
Therefore, if f represents the fee in dollars of a trip they climbed d vertical meters then we can model the situation as
f = 100 + 0.133d (Answer)
