Answer:
D) h = A/2πr - r
Step-by-step explanation:
A = 2πr(r+h)
A = 2πr² + 2πrh
2πrh = A - 2πr²
h = (A-2πr²)/2πr
=A/2πr - 2πr²/2πr
=A/2πr - r
Vertical angles are angles opposite of eachother and therefore the same. Since angle 2 is 93° that means angle 1 must also be 93°
The expression is written as (4n/9) + 14
What is an expression?
An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. To assist identify the sequence of operations and other features of logical syntax, mathematical symbols can denote numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. Many writers differentiate between an expression and a formula, with the former referring to a mathematical item and the latter referring to a statement about mathematical things. For instance, is a formula. However, in modern mathematics, and particularly in computer algebra, formulae are considered as expressions that may be evaluated as true or false based on the values assigned to the variables in the expressions.

To get the the cost of how much Alexis is paying we first have to find the original cost and then subtract the $15 which is equal to 20% of the original number.
To find the original price you take the $15 and divide it by .20
15÷.20= 75
To get the original price of a percentage you do the opposite of if you were trying to find the % for example :
75 x .20 = 15
15 ÷ .20 =75
The original price is $75
75 - 15 = 60
With the discount it is $60
I hope it helped
If the product of two integers is negative that means that the integers that were multiplied together consisted of a positive integer and a negative integer.
Ex: -2 X 4 = -8
