Answer:
The value of each expression when x=3 will be -20 and -20.
Step-by-step explanation:
Given the expression
-4x-8
setting x=3
= -4(3)-8
=-12-8
=-20
Given the expression
-2(x+1)-2(x+3)
setting x=3
=-2(3+1)-2(3+3)
=-2(4)-2(6)
=-8-12
=-20
so we conclude that the value of both the expressions was -20 when we substituted the value x=3.
Therefore, the value of each expression when x=3 will be -20 and -20.
Answer:
A town with 600 people need 10 firefighters
A town with 1500 people will need 1500 x 10/600 = 1500/60
= 25 firefighters

If the factors of quadratic function f are (x – 7) and (x + 3). The solution of the quadratic function f will be the negative 3 and 7.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
If the factors of quadratic function f are (x – 7) and (x + 3).
Then the zeroes of function f will be
(x – 7)(x + 3) = 0
x = 7, -3
Then the solution of the quadratic function f will be the negative 3 and 7.
