The answer is
<span>−(x−1)(x+9)=0
</span><span>3x^2−6x=0
According to the zero product property:
If a * b = 0, then either a = 0 or b = 0
If </span>−(x−1)(x+9)=0, then either x - 1 = 0 or x + 9 = 0
<span>3x^2−6x=0 need to be written in factor form:
x(3x - 6) = 0
So if </span>x(3x - 6) = 0, ten either x = 0 or 3x - 6 = 0
The written form is one hundred and twenty one point zero six
I would use the quadratic equation for this.
Answer:
Step-by-step explanation:
hello :
f(n)=f(n-1)+2
means : f(n)-f(n-1)=2
this is the arithmetic seq when the common dif is d= 2 and the first term is : 9
the n-ieme term is : f(n) = f(1) +(n-1)d
f(n) =9+2(n-1)
f(n) = 2n+7
so : f(5) = 2(5)+7 = 17
Answer:
C
Step-by-step explanation:
according to sine rule,
sin(30)/8=sin(x)/11
solving above equation will give
x=43.3
