Answer:
x² + 10x + 24
Step-by-step explanation:
Use foil to multiply them.
x ( x + 4 ) = x² + 4x
6 ( x + 4) = 6x + 24
Combine like terms: x² + 10x + 24
Hope this helps :)
Actually, when you know 2 sides and an included angle, you use the Law of Cosines. (and we don't know if theta is an included angle).
Solving for side c
c^2 = a^2 + b^2 -2ab * cos(C)
c^2 = 36 + 16 - 2*6*4 * cos(60)
c^2 = 52 -48*.5
c^2 = 28
c = 5.2915
Using the Law of Sines
side c / sin(C) = side b / sin (B)
5.2915 / sin(60) = 4 / sin (B)
sin(B) = sin(60) * 4 / 5.2915
sin(B) = 0.86603 * 4 / 5.2915
<span><span>sin(B) = 3.46412
</span>
/ 5.2915
</span>
<span><span><span>sin(B) = 0.6546571451

Angle B = 40.894 Degrees
sin (A) / side a = sin (B) / side b
sin (A) = 6 * sin (40.894) / 4
sin (A) = 6 * 0.65466 / 4
sin (A) = .98199
angle A = 79.109 Degrees
angle C = 60 Degrees
Answer:
$2.95 for a small popcorn
Step-by-step explanation:
you do 8 multiplied by $7.50
which gives you $60 for the total spent together on tickets and then you do
$60 minus the total cost which is $83.60 and you get $23.60 left and then
you divide $23.60 by 8 because there is 8 people and you get a total of 2.96 for a popcorn
