Answer:
x = 3,-5 is correct.
Step-by-step explanation:
The Zero Product Property:
The Zero Product Property simply tells that if a*b=0, it implies that either a=0 or b=0 (or the both of them must be equal to zero). The product of the factors is zero if and only if the one or more of factors is zero. This is particularly useful for solving the quadratic equations .
In the given question the quadratic equation is (x-3)(x+5)=0
from the Zero Product Property, it is clear that x-3 =0 or x =3
x+5 =0 or x=-5
Therefor x = 3,-5 Hence option 3 is correct.
I think its hexometer because hex means 6.
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
Step-by-step explanation:
Combine the like terms. move over the -3x to the right and it’s now 3x and combine it with -2x to get x. Move the 4 over to the left and it becomes -4 and combine it with the 1 to get -3. Then you are left with -3=x
Answer:
$143,370 per month
Step-by-step explanation:
16495 + 8.75(14500) = x
16495 + 126875 = x
143370 = x
Answer: $143,370 per month
Hopefully this is right
