Answer:
x = - 2, x = 7
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² - 5x - 14 = 0 ← in standard form
(x - 7)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 7 = 0  ⇒ x = 7
x + 2 = 0 ⇒ x = - 2
 
        
             
        
        
        
C because it simplifies to 0=0 which proves that it has infinite solutions!
        
                    
             
        
        
        
Y=(x+1)(x-4)
this should be correct.
        
             
        
        
        
Answer: 208 in^2
Step-by-step explanation:
find the surface area of the square base
8(8)=64
find the surface area of the 4 triangular lateral faces
SA=4(bh÷2)
4(8 x 9 ÷2)
4(36)=144
add the surface area of the square base and lateral faces
64+144=208
