Firstly, foil -3(w + 12): 
Next, combine like terms: 
Next, add 36 on both sides of the equation: 
Lastly, divide both sides by -14, and <u>your answer will be 
, or approximately (rounded to the hundreths) -2.93.</u>
Answer:
2/3
Step-by-step explanation:
Ratio is 2:3 since we have 6 and 9 for width. We can refer to 1:2:3 as 3:6:9, and apply the same thing for length 8 to where we have 4:8:12.
Answer:
5.833
Step-by-step explanation:
Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
