As far as 2) check the picture below, solve for "x"
what's the angle "3m"? well, 3m = 12x + 40, those two angles are equal, since it's an isosceles trapezoid
f(x)=-3x+2, for x = 3
Replace x with 3 in the equation and solve:
-3(3) + 2 = -9 + 2 = -7
The answer is -7
Answer:
A and C
Step-by-step explanation:NLE Choppa said so
Arc length = radius * central angle (in radians)
arc length = 12.6 * 2*PI/7
arc length = 25.2 * PI/7
<span>arc length = 11.31 feet
