Make equal to 0
minus 12from both sides
x^2+10x+13=0
we can't factor so use quadratic formula

x=-1.5359 or -8.4641
Answer:
x=1+4/5 this is the answer i think
Answer:
168 pages
Step-by-step explanation:
each night you read 28 pages, so 6 nights you have to read for 28x6=168 pages.
If 2 + 5i is a zero, then by the complex conjugate root theorem, we must have its conjugate as a zero to have a polynomial containing real coefficients. Therefore, the zeros are -3, 2 + 5i, and 2 - 5i. We have three zeros so this is a degree 3 polynomial (n = 3).
f(x) has the equation
f(x) = (x+3)(x - (2 + 5i))(x - (2 - 5i))
If we expand this polynomial out, we get the simplest standard form
f(x) = x^3-x^2+17x+87
Therefore the answer to this question is f(x) = x^3-x^2+17x+87
I = p * r * t
264 = p * .06 * 2
264 = .12p
Divide both sides by .12
p = $2200
