Answer:
11.4
Step-by-step explanation:
d² = 6² + 6² - 2(6)(6)cos145
d² = 130.9789472
d = 11.44460341
Cos(x)= adjacent/hypotenuse
cos(18)=x/25 (cross multiply)
25*cos(18)=x
x= 23.78 cm <--- this is rounded to the nearest hundredth.

Answer:
B
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then the graph opens upwards
• If a < 0 then the graph opens downwards
y = x² + 5x + 6 ← is in standard form
with a = 1 > 0
The graph therefore opens upward
