Do yall want free points, brainliest, 5 stars, and a thanks? Well then answer the question then! I have 81 points.

Can someone check if i did this correct. it’s number 4 if you’re wondering.

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0
