Answer: x = 57
Step-by-step explanation:
Since CD = AC, triangle ACD is isosceles, therefore
ADC = DAC
ADC + DAC + 112 = 180
ADC + DAC = 180 -112 = 68
ADC + DAC = 68/2 = 34
DEB = 180 - 34 - 23 = 123 (sum of interior angles of a triangle = 180)
Therefore, x = 180 - 123 = 57 (DEB and x are supplementary angles)
Well to factor a trinomial (Which is in the form ax^2 + bx + c) You would have to bring the A over to c so you can get x^2 alone. (If their isn't a gcf) You could also try to find what multiplys ac to add to b. but since that is not possible you would rewrite it x^2 -27x + 72 ( by multiplying the a to c) The you would rework it as normal (whatever two numbers multiply to 72 and add to -27. Which would be (x-3)(x-24). Then you would divide by the original A (x-3/18)(x-24/18). Then you would simplify that. (x-6)(x-4/3) and you would take any extra denominators and bring it to the front of the x. Making it (x-6)(3x-4)
The question says "about" so we will be rounding the numbers.
48 roses = 50 roses
39 tulips = 40
50 + 40 = 90. So she planted about 90 tulips and roses
