Step-by-step explanation:

the correct formula for this is the heron's formula

which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2

s=√(13.5-12)(13.5-9)(13.5-6)

s=√(1.5)(4.5)(7.5)

s=√50.625

s= 7.11 or 7 to the nearest square unit

What equation can be used?

Kryger [21]

Answer:

$f(x)=89x+1800$

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

$f(x)=89x+1800$

Consider the functions f(x)=(ax^2-b)/(x^2-4) and g(x)=(x^2-cx+d). if the limit as x approaches 3 equals 6, what is the relations

Dmitry_Shevchenko [17]

$6=\dfrac{a\cdot3^2-b}{3^2-4}\\\\
6=\dfrac{9a-b}{5}\\\\\
9a-b=30\\\\
