Answer:
5/24
Step-by-step explanation:
Start with the first part of the probelm 5/6 - 2/3
You need to find a common denominator of 6 and 3
common denominator= 6
so change 2/3 to 4/6
now you can subtract the top values
5/6-4/6
5-6=1
keep the denominator the same
= 1/6
Now divide 1/6 by 4/5
to divide you are going to multiply by the reciprocal so instead of 4/5 we are going to flip it to 5/4
1/6 x 5/4
5x1=5 and 6x4=24
= 5/24
Supplementary angles always equal 180. Then you just solve from there.
7x+5x+24=180
12x+24=180
-24 -24
12x=156
/12 /12
X=12
Second option:
-7x^2+4x+2
