At a fair there are 18 game booths and 27 food booths. The fee for a food booth is $75 plus $5 per day. The fee for a game booth is $50 plus $8 per day. The fair lasts for d days, and all of the booths are rented for the entire time. Write and simplify an expression for the amount in dollars that the company is paid.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

a - base

b - exponent

is this a dating site too?

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
