Answer: The sum of the equation is 18
Step-by-step explanation:
Step by step explanation
4n-8=5
4n= 5+8
4n=13
4/4 n = 13/4
n= 13/4
Of means multiply in math (most of the time).
So multiply.
2/5 x 7/10 = 14/50 divided by 2/2 = 7/25
29.

As
,
.
This can be easily verified by looking at the graph (graph of a quadratic equation).
30.
The growth of a population is not linear, it's exponential.
31.
Exponential growth > polynomial, so
.
35.

The question is asking V(t) for t = 40.

36.
The point of symmetry of a quadratic equation
is at its vertice:



The line is x= 3.
