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.
7 * 9 = 63

Answer:
2.25 GB
Step-by-step explanation:
You and your brother each spend 0.75 GB per month, meaning that together you spend 1.5 GB.
Subtract this from the total to find the remaining amount of data left:
6 - 1.5 = 4.5 GB
Assuming your mother and father split the remaining data equally, simply divide the remaining amount by 2 to find your answer:
4.5 / 2 = 2.25
Therefore, your parents can each use 2.25 GB.
33.
We have an isosceles triangle, which means that two of the sides of the triangle are equals, the same is with the angles
side LM= side MN
angle L =angle N
Also we need to remember that the sum of the interior angles of a triangles is 180°
angle M=120
angle N=x
angle L=x
120+x+x=180
2x=180-120
2x=60
x=60/2
x=30
m < M =120°
m< N=30°
Hold down the Shift and press F3 . When you hold Shift and press F3, the text toggles from sentence case (first letter uppercase and the rest lowercase), to all uppercase (all capital letters), and then all lowercase.
