well, the quadratic has a leading term with a positive coefficient, meaning is a parabola opening upwards, like a "bowl", comes from above down down down, reaches a U-turn, namely the vertex, and goes back up up up.
so the minimum value is at the vertex of course, and the minumum is well, just the y-coordinate of the vertex, 8.
9x+27+15x
24x+27
Nine times x equals nine x. Then nine times three equals twenty-seven. Combine nine x and fifthteen x and you get twenty-four x.
The eqaution i use for this is:
(cross multiply)
(25.83)(100) = (x)(49.5) (multipy)
2583 = 49.5x (divide by 49.5 on both sides)
52.181818182 = x

Answer:
a = 95
Step-by-step explanation:
a+ 35+ 50 = 180
Combine like terms
a+ 85 = 180
Subtract 85 from each side
a+85-85 = 180-85
a = 95
