The first step is finding the unit rate. We can do this by evaluating
21/1.75 divided by 1.75/1.75.
When you divide the two, you get 12.
To check your work you do 12(1.75) and you will get 21
So first you plug 6 into the equation which is 4(6)-10.
Using PEMDAS, you solve what’s in the parenthesis first and you get 24-10.
24-10=14
f(6)=14
Answer:

Step-by-step explanation:
I think the answer choices were supposed to be:

Pythagorean Theorem: a²+b²=c²
5²+b²=8²
25+b²=64
<em>Subtract 25 from both sides</em>
b²=39
<em>Square root both sides</em>
b=
