Here's the question ​
zheka24 [161]

Answer:

60

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60

Which is the function represented by the table? A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, neg
Serggg [28]

Answer:

f(x)=4x

Step-by-step explanation:

Given: See the attached image

To find: the function represented by the table

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

f(-2)=-8=4(-2)\\f(-1)=-4=4(-1)\\f(0)=0=4(0)\\f(1)=4=4(1)

Here, -2,-1,0,1 are elements in the domain and -8,-4,0,4 are elements in the co-domain.

Therefore, the table represents the function f(x)=4x

Simplify the rational expression. state any excluded values. 4x - 4/ x - 1
grin007 [14]
We need to simplify this expression:

\frac{4x-4}{x-1}

So, we will call this expression as:
f(x) = \frac{4x-4}{x-1}

We can write this equation like this:

f(x) = \frac{4(x-1)}{(x-1)}

So, if we simplify it, this can be written like this:

f(x) = 4 but given that the denominator can't be zero, then:
x-1 \neq 0 ∴ x \neq 1 

Therefore:
f(x) = 4 if and only if x \neq 1
