Answer:
a^2-1
Step-by-step explanation:
(a+1)(a-1)
=a^2-1
Answer:
0.008
Step-by-step explanation:
because you have to divide it
The average rate of change = 1.59 ≈ 2
The average rate of change can be calculated by
1) The first one =
= 1.5
2 ) the second can also be solved by ; 8 + 2/ 2 = 5
3 ) the third one will be 20 + 6 / 2 = 13
4) 8.5
5) 12.5
To calculate the average rate of change
we will first add all the distance
Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51
The total time = 2 + 6 + 9 +15 = 32
Thus the average rate of change = 51 / 32 = 1.59

Let's talk about the choices
◯ ∠4 and ∠5 . . . . . . . . these are complementary angles whose sum is 90°
◯ ∠7 and ∠9 . . . . . . . . these are vertical angles, equal to each other
◯ ∠2 and ∠3 . . . . . . . . these are supplementary angles that together form a straight line. They are a linear pair.
◯ ∠1 and ∠2 . . . . . . . . these are "adjacent" angles in the quadrilateral that also includes ∠9 and ∠10.
The appropriate choice is ...
◉ ∠2 and ∠3
Answer:
the answer is A because the cost of the more expensive one is 15+20=35 multiplied by 3 which will give me =$105
And the cheaper one is 15+20=35 multiplied by 1.50 = which is 52.5
so the amount more of the choice for the more expensive one is 105-52.5=52.5.
the answer is 52.50.
