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.
The answer is /6 radians. I looked up the unit circle hope this helps :)
Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2
Answer:
y = 12x + 9
Step-by-step explanation:
you triple 4x and just add nine because the y intercept is zero
