A product of two (or more) factor can be zero if and only if at least one of the factors is zero.
In other words, you cannot multiply two non-zero real numbers, and have zero as a result.
So, if we want the product of these two factors to be zero, at least one of them has to be zero.
The first factor is zero if
The second factor is zero if
The solutions to the equation are x = 2 and x = -5.
To find the solutions to the equation (x – 2)(x + 5) = 0, you need to set each factor equal to zero and solve for x. When the product of two factors is equal to zero, one or both of the factors must be equal to zero.
Set x - 2 = 0 and solve for x:
x - 2 = 0
x = 2
Set x + 5 = 0 and solve for x:
x + 5 = 0
x = -5
The solutions to the equation are x = 2 and x = -5. When you substitute these values back into the original equation, you get (2 - 2)(2 + 5) = 0 and (-5 - 2)(-5 + 5) = 0, both of which evaluate to 0, confirming that these are indeed the solutions.

Answer:
$728.00
Step-by-step explanation:
10m*14m=140m
140*$5.20=$728.00
.15x=12
x= 12/.15
x= 80
15% of 80 equals 12
I hope that's help !
