Answer:
Step-by-step explanation:
F(x)=(5 t^2+t  )x to x+3
=5((x+3)^2-x^2)+(x+3-x)
=5(x^2+6x+9-x^2)+3
=5 (6x+9)+3
=30x+48
F'(x)=30
 
        
             
        
        
        
The statement is False.
 For this, it is enough to show a case in which the subtraction of two positive numbers is negative.
 For this, we must choose two numbers.
 Suppose we want to subtract the following numbers:
 Number 1: 5
 Number 2: 10
 Subtracting both numbers we have:
 
 We observe that the result is negative. Therefore, the given conclusion is false.
