First step is distribution:

-(6-5n)+12

-6+5n+12

5n+6=-6+5n+15

Second step combine like terms:

5n+6=5n+9
-6 -6

5n=5n+3

0=3

5x + 12 + 3x = 6(x + 4) Please Show Work.

Len [333]

5x + 12 + 3x = 6(x + 4)

5x+3x+12=6(x+4)

Multiply the bracket by 6

(6)(x)(6)(+4)=6x+24

5x+3x+12=6x+24

8x+12=6x+24

Move 6x to the other side. Sign changes from +6x to -6x.

8x-6x+12=6x-6x+24

8x-6x+12=24

2x+12=24

Move 12 to the other side. Sign changes from +12 to -12.

2x+12-12=24-12

2x=12

Divide by 2 for both sides.

2x/2=12/2

x=6

Answer: x=6

8-10 deal with the ambiguous SSA case. for each find all possible solutions and sketch the triangle in each case.

Artist 52 [7]

For problem 8:

sin A/a sinB/b = sinC/c

so sin50/15 = sinB/12

0.766/15 =sinB/12

0.051066 = sin B/12

sin B = 0.6128
B = 37.79 degrees

sum of angles must equal 180 deg therefore C = 180-50-37.79 = 92.21 degrees and .766/15 = sin92.21/c

.051066= 0.99925/c
c = .99925/0.051066 = 19.567

Problems 9 and 10 can also be done with the same method as problem 8.
