Area is 9 x 3.14 = 28.3
C = 6 x 3.14 = 18.8
Answer:
Option 4
The term that represents the amount of time that the money is accruing interest is 'x'.
Step-by-step explanation:
Given : The function below represents the annual interest Alexander earns on a savings account.
To find : Identify the term that represents the amount of time that the money is accruing interest ?
Solution :
The general annual interest formula is
Where, A is the amount
P is the principal
r is the interest rate
t is the time
The annual interest Alexander earns on a savings account is
Comparing with general formula,
t=x
The term that represents the amount of time that the money is accruing interest is 'x'.
Therefore, Option 4 is correct.
Let's treat that one as a 4 by 8 rectangle with a 2 by 4 right triangle chopped out of the corner.
A = 4×8 - (1/2)×2×4 = 32 - 4 = 28
Answer: 28
Answer:
Go through the explanation you should be able to solve them
Step-by-step explanation:
How do you know a difference of two square;
Let's consider the example below;
x^2 - 9 = ( x+ 3)( x-3); this is a difference of two square because 9 is a perfect square.
Let's consider another example,
2x^2 - 18
If we divide through by 2 we have:
2x^2/2 -18 /2 = x^2 - 9 ; which is a perfect square as shown above
Let's take another example;
x^6 - 64
The above expression is the same as;
(x^3)^2 -( 8)^2= (x^3 + 8) (x^3 -8); this is a difference of 2 square.
Let's take another example
a^5 - y^6 ; a^5 - (y ^3)^2
We cannot simplify a^5 as we did for y^6; hence the expression is not a perfect square
Lastly let's consider
a^4 - b^4 we can simplify it as (a^2)^2 - (b^2)^2 ; which is a perfect square because it evaluates to
(a^2 + b^2) ( a^2 - b^2)
The formula for perimeter is 2L +2W
Replace w with 20 and L with 11:
2(11) + 2(20) = 22 + 40 = 62
This does not equal 64, so the perimeter cannot be 64 with 20 and 11 being the dimensions.
