2(3a+4)=6a+8 demonstrates the distributive property.
Answer:
x=11
Step-by-step explanation:
These add up to 180 since a straight line = 180 degrees
Your equation is: 4x+15+11x=180
15x+15=180
15x=165
x=11
The temp. rose by 25 degrees. divide that by 5 and it equals 5. so, add 5 hours to four o clock and you get 9:00
Answer:
BC = 6.9
Step--step explanation:
Reference angle = 30°
Adjacent = BC
Hypotenuse = 8
Apply trigonometric function, CAH:
Cos 30° = Adj/Hypotenuse
Cos 30° = BC/8
8*Cos 30° = BC
6.92820323 = BC
BC = 6.9 (to the nearest tenth)
