Answer:

A = 55.63 cm^2

Step-by-step explanation:

Let a,b,c be the lengths of the sides of a triangle. Heron's formula states that:

Area = √(p (p−a) (p−b) (p−c))    

where p is half the perimeter, or    

(a+b+c) / 2

So lets start by finding p:

(10.6 + 10.6 + 16) / 2

p = 18.6

Now lets substitute p and the other values into our equation:

A = √ (18.6 (18.6−10.6) (18.6−10.6) (18.6−16))

So let's plug this in to our calculators

A = √ (3095.04)

A = 55.633083682284 cm^2

Will give brainlest plz help!!!Which relation is a function?
Levart [38]

The correct answer is the graph in the top right corner because it is a constant function. The bottom left graph is also considered a function but is an absolute function. So both are technically correct.

Four times the quotient of a number and 9 plus 14, how do I right it as an expression?
user100 [1]

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.

The expression is written as (4n/9) + 14
