Answer:
Option B.
Step-by-step explanation:
The given quadratic equation is
We need to find the solution of given quadratic equation.
Divide both sides by 9.
Taking square root on both sides.
The solution of given equation are and
.
Therefore, the correct option is B.
Let's say the numbers are "a" and "b"
hmm say "a" is the smaller, and "b" the greater
so "b" is "4 more than 5 times" "a"
so... 5 times "a" is 5*a or 5a
4 more than "that", will be "that" + 4
or
5a + 4
so.. whatever "a" is, "b" is 5a+4
now, their sum is 22, as opposed to "zz" hehe
so
solve for "a", to see what the smaller one is
what's "b"? well, b = 5a + 4
