Simply will say
4000(3.5%) = 140 km^2
So each year will decrease by 140km^2
To find till 9th years it will be
4000-(140*9)=2740 km^2
Area after 9 years is 2740 km^2
The answer is -2x^2-7x-11
you just have to add the ones that have the same variable with the same exponent. so you would add -5x^2 and 3x^2 which is -2x^2.
Then you add -3x and -4x which is -7x.
in the end you only have to add -8 and -3 which is -11
Given :
A local company offers a monthly plan for 58.95 dollars.
The company is having a sale and offering a discount of 4.75 off the monthly plan.
To Find :
Sam says that the new cost is 11.45 explain Sam's error and find the correct new cost.
Solution :
Correct cost = Original price - Discount offered
Correct cost = $( 58.95 - 4.75 )
Correct cost = $54.2 .
Now, Sam's cost is $11.45 because he took $4.75 as $47.5 .
Hence, this is the required solution.

How to find the derivative of a root?<span>Use the rule to differentiate the following example, first simplifying the root and writing it as a fraction using the notation. Move 7/6 forward then decrease the power by 1. Use the definition of a derivative to differentiate f(x) = x^–1 = 1/x. First simplify the numerator then simplify and cancel as much as possible.</span>
