Answer:
yes
Step-by-step explanation:
There are several ways to go at this.
My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.
Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.
(((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0
The value of h(5) is zero, so x-5 is a factor of h(x).
Answer:
C) The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
sqrt(b² - 4ac) is not equal to
b - sqrt(4ac)
Because when you square b - sqrt(4ac), it's not b² - 4ac..
(b- sqrt(4ac))² = b² - 2bsqrt(4ac) + 4ac
Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups
Hope this helped!
Answer:
B is the answer
Step-by-step explanation:
A = πr²
24π = πr²
24 = r²
24 = r²
= r
r = 
= 2
C = 2πr
C = 2π(2)
C = 4π
