Answer:
Step-by-step explanation:
hello :
y = x² + 12x + 5
y = ( x²+12x+36) -36+5
y= (x+6)²-31.......vertex form when the minimum possible value is : - 31
Answer:
x=2
Step-by-step explanation:
-3*(x-2)-(2*x-3)-(5-(4*x-2))=0
((0 - 3 • (x - 2)) - (2x - 3)) - (7 - 4x) = 0
2 - x = 0
-x+2 = 0
Subtract 2 from both sides of the equation :
-x = -2
Multiply both sides of the equation by (-1) : x = 2
Answer:
Step-by-step explanation:
Sum of all exterior angles = 360°
Size of one exterior angle = 40°
Number of sides = 360 ÷ 40 = 9
