Bob covered both sides of his roof with a tarp. His roof rises 6 feet above the eaves and is 40 feet
wide. The tarp fits exactly from side of the roof to the other. Approximately how wide is the tarp?
(Round to the nearest whole number.)

Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
