You are solving for the height. Use the formula:
c² - b² = a² in which c = hypotenuse
(13)² - (5)² = a²
Simplify
169 - 25 = a²
144 = a²
Isolate the a. Root both sides
√144 = √a²
a = √144
a = √(12 x 12)
a = 12
C) 12 feet is your answer

Answer:uidelines called the order of operations, which outlines the order in which parts of an expression must be simplified.
ORDER OF OPERATIONS
When simplifying mathematical expressions perform the operations in the following order:
1. Parentheses and other Grouping Symbols
Simplify all expressions inside the parentheses or other grouping symbols, working on the innermost parentheses first.
2. Exponents
Simplify all expressions with exponents.
3. Multiplication and Division
Perform all multiplication and division in order from left to right. These operations have equal priority.
4. Addition and Subtraction
Perform all addition and subtraction in order from left to right. These operations have equal priority

Answer:
it knocks off $179.80 or the final cost which is $719.20.
Step-by-step explanation:
Y=10(3)^3-12(3)
y=270-36
y=234
5 for $3.50 has the lowest unit price because 3 for $2.19 is $0.73 per item, 4 for $3.00 has a in it price at $0.75, 5 for $3.50 has a unit rate for $0.70 per item, and $0.72 per item is more expensive than $0.70 per item
