Answer:
im pretty sure you just divide the amount of money byt the amount it costs
Step-by-step explanation:

Taking 4 out from first two terms, we will get

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

Distributing 4

Cancelling 9

And that's the required standard form.
A. 0.58 is the corresponding index of the random matrix of 7 criteria for checking the consistency of random judgment.
In probability theory and mathematical physics, a random matrix is a matrix-valued random variable. H. A matrix whose elements are some or all random variables. Many important properties of physical systems can be represented mathematically as matrix problems.

The coefficient of the variable......the variable is a letter subbed in for an unknown number.....so the variable is x....the coefficient is the number multiplied by the variable....so that is -5.
The equation is given to compute A(7) = A(r) pi r²
7 = pi r²
r² = 7/pi
value of pi = 3.14
so,
r² = 7/3.14
r = √ (7/3.14)
r = 1.49
