Determine if the following sets of quadratics are equivalent. choose true or false. x^2 - 10x + 14 = 0 and (2x - 10)^2 = 156 (x - 10)^2 = 68 and x 2 - 20x = -32 x^2 - 6x = 247 and (x - 3)^2 = 256 (x + 5)^2 = 65 and x^2 = 90 - 10x

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
