<u>Step-1: Subtract 1/4 both sides</u>
Answer:
4(x-4.5)^2
Step-by-step explanation:
h(x)=4x^2-36x+81
=4(x^2-9x)+81
=4(x^2-9x+20.25)-(4)(20.25)+81
=4(x-4.5)^2
Okay so the value of X is 9x^2/7
Answer:
Step-by-step explanation:
Let that number be . We can build an equation, and solve for .
less than half of is .
more than is .
We are given that the two quantities are equal, so we have that .
Adding to both sides gives .
Multiplying both sides by gives .
Subtracting from both sides gives .
Multiplying both sides by gives .
So, the number is and we're done!
The check is left as an exercise to the reader.
