Answer:
The standard form of quadratic equation is 
The factored form of is 
Step-by-step explanation:
Given equation 
We have to write in standard form and then factorize the given equation.
The standard form for a general quadratic equation is given as 
Consider
Taking all terms to left side, we have,
Adding like terms, we have,
Now we will factorize it.
We will solve the quadratic equation using middle term splitting method,
-16x can be written as -18x+2x
becomes
Taking x common from first two terms and 2 common from last two terms we have,
Thus, the factored form of is
Answer:b
Step-by-step explanation:

the second option
Step-by-step explanation:
The <em>correct answer</em> is:
D) Using cash can make it easier to over-spend since you know exactly how much you have.
Explanation:
Knowing exactly how much you have on hand will actually help you avoid over-spending.
When using cash, you are aware of exactly how much money you have. With a credit card, this may not be the case; this makes it easier with a credit card to spend more money than you should for your budget. With cash it's easier to avoid this problem.
C=10pi
C=2(r)pi so r=5
A=pi(r)^2
so A=pi(5)^2
A=25pi
