Step-by-step explanation:
I'll do 2.
Alright,Alex let say we have factored a quadratic into two binomial, for example
If we set both of those equal to zero
We can used the zero product property in this case to find the roots of the quadratic equation.
This means that
This means we set each binomal equal to zero to find it root.
So our roots are negative 3/5 and negative 2/3 using zero product property
The answer to your question is 2.3
Answer:
52 years old
Step-by-step explanation:
let this mans age be a
400-3a=244

To begin with, equivalent fractions represent the same part of a whole number. So I need to find a fraction, with a denominator of 20, that is the same value as 1/2:
1/2 = ?/20
1*10/2*10 = 10/20
Since the denominator needed to be 20, I multiplied the numerator and the denominator (1/2) by 10 to get 10/20. So, 1/2 and 10/20 are equivalent.
