Answer:
if f(x)= -4x+3
f(-5)= 23
Step-by-step explanation:
first you substitute x for -5
f(-5)= -4(-5)+3
then you multiply
-4(-5)
f(-5)=20+3
you get the positive 20 because negative times negative equals positive
then you just add the rest (20+3) which will give you your answer
f(-5)= 23
Answer:
The Width of the Rectangle =

Step-by-step explanation:
The area of the rectangle 
We are told that the width of the rectangle is equal to the greatest common monomial factor of 
Let us determine the greatest common monomial factor of 
Express each term as a product to pick out the common factors:

In the two terms, the common terms are 10 and
. Therefore their greatest monomial factor =
The Width of the Rectangle =
Recall: Area of a Rectangle =Length X Width

30.50-14= 16.50
16.50 divided by 2.75= 6
The answer is 6
