Solve x2 − 7x + 12 = 0. a. x = −3, x = −4 b .x = 3, x = 4 c. x = 2, x = 6 d. x = −2, x = −6

Factor and use the zero product property. To factor, find two numbers that multiply to +12 and add to -7. These two numbers are -4 and -3

So,
x^2 - 7x + 12 = 0
(x-4)(x-3) = 0
x-4 = 0 or x-3 = 0
x = 4 or x = 3

Answer is choice B

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
