Answer:
a = 2
Step-by-step explanation:
given x = - 1 is a zero then f(- 1) = 0 , that is
a(- 1)³ - (- 1)² - 1 + 4 = 0
- a - 1 - 1 + 4 = 0
- a + 2 = 0 ( subtract 2 from both sides )
- a = - 2 ( multiply both sides by - 1 )
a = 2

Answer: The answer is 60 square inches.
Step-by-step explanation:  Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.
The area of one triangle is given by

Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be

Thus, the answer is 60 sq. inches.
 
        
                    
             
        
        
        
Answer:
a. 12 minutes 
b. 34 minutes 
Step-by-step explanation:
Here, we are told that Ima has driven 5 minutes before Polly started driving 
So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5
So mathematically;
x = y + 5
a. 17 = y + 5
y = 17-5 = 12 minutes 
b. x = 29 + 5
x = 34 minutes
