see explanation
Step-by-step explanation:
let n and n + 2 be 2 consecutive even numbers , then
(n + 2)² - n² ← is the difference
= n² + 4n + 4 - n²
= 4n + 4
= 4(n + 1) ← a multiple of 4

Answer:
Step-by-step explanation:
Given the length of a fish after t years modeled by the equation
L(t) = 9 − 1/5t
The average rate of growth is expressed as;
dL/dt = -1/5 (differential of a constant is zero)
Hence the average rate of growth over the first year of life is -1/5 in/year
Answer:
28
Step-by-step explanation:
To begin, lets make an equation out of this problem,
x/32 = 7/8
Then, let's solve for the variable x or AKA the missing value
x/32 x 32 = 7/8 x 32
x = 28
So, there is the answer, the missing value is 28
