Answer:
The zeros of the given function are -9,-1 and 12.
Step-by-step explanation:
The given function is

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.
Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).




Use zero product property and quote each factor equal to 0.

Therefore zeros of the given function are -9,-1 and 12.
Answer:
See answers below.
Step-by-step explanation:
For formula to find the volume of rectangular prism is given below:

11. Putting the given values, we have:


Everything except for 4 is correct, number 4 is c.
Let the width be W, then the length is 4W (since the width is 1/4 the length)
The area of the original deck is

The dimensions of the new deck are :
length = 4W+6
width=W+2
so the area of the new deck is :

"<span>the area of the new rectangular deck is 68 ft2 larger than the area of the original deck</span>" means that we write the equation:




the length is

ft
Answer: width: 4, length: 16

Answer:
Rajan gets 6 marks more
Step-by-step explanation:
Neerav's marks are (15)(4) +(5)(-2) = 60 -10 = 50.
