Answer:
AB = 8.0
Step-by-step explanation:
Law of Sines
AB/sin53 = 7/sin44
multiply both sides by sin53
AB = 7/sin44 * sin53
use calculator
AB = 8.047766798861355
Rounded
AB = 8.0
Answer:
38 yards²
Step-by-step explanation:
Area of trapeziods= ½(a+b)×height
a and b are the parallel lengths of the trapezoid.
Area of trapeziod= ½ (5.6+13.4)×4= 38 yards²
Therefore, the correct option is B

The factored form of this quadratic would be : (2x - 5)(x + 3) you can use the foil method to multiply the binomials to verify.
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
