Answer:
Step-by-step explanation:
8 = 2 × 2 × 2
4 = 2 × 2
LCM = 2 × 2 × 2
LCM = 8
3 = 3 × 1
6 = 2 × 3
LCM = 2 × 3 × 1
LCM = 6
66 = 2 × 3 × 11
72 = 2 × 2 × 2 × 3 × 3
GCF = 2 × 3
GCF = 6
I believe the answer is y=5x-4
x^2 +x(7+3) +21
x^2 +7x + 3x +21
x(x+7) +3(x+7)
(x+7) (x+3)
take 22 degree as reference angle
using cos rule
cos 22=adjacent/hypotenuse
0.92=56/x
x=56/0.92
x=60.86
x=60.9
