Answer:
f(x) = (x + 10)(x + 4)(x - 1)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a and x = b, then
the factors are (x - a) and (x - b)
The polynomial is then the product of the factors
f(x) = (x - a)(x - b)
Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are
(x - (- 10)), (x - (- 4)) and (x - 1), that is
(x + 10), (x + 4) and (x - 1)
f(x) = (x + 10)(x + 4)(x - 1)
 
        
             
        
        
        
The total value of all coins together is $2.7
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line
Let the number of nickels and quarters be x.
Value of nickel = 5 cents = $0.05
Value of quarters = 25 cents = $0.25
Thus, the total value equals
0.05x +$1.80 = 0.25x
$1.80 = 0.25x - 0.05x 
$1.80 = 0.2x
x = 1.80/0.2 
x = 9 coins
Thus the total value of all coins together is  ($0.05+$0.25)x 9 = $0.3 x 9
=  $2.7

Answer:
C
Step-by-step explanation:
Given
x³ + 3x² + 3x + 9 ( factor first/second and third/fourth terms )
= x²(x + 3) + 3(x + 3) ← factor out (x + 3) from each term
= (x² + 3)(x + 3) → C
