Simplify the equation as best you can and then graph it. When you have graphed it, the x-coordinate when y=0 is x.
Answer:6a+75
Step-by-step explanation:
5+2a+22+22+1+1+22+4a+3
add 22,22,1,1,22,5, and 3
2a+4a+75
6a+75
Answer:14
Step-by-step explanation:
Since O is inscribed in triangle ABC, you know that AB, AC, and BC are all tangent to the circle. The tangent segments theorem asserts that AD is congruent to A F; BD is congruent to BE; and CF is congruent to CE. (NOTE: E is the point where the circle touches BC - I've taken the liberty of labeling it as such.)
Then the perimeter 
of triangle ABC will be twice the sum of the labeled edges:
Answer:
487.5 miles
Step-by-step explanation:
since 1/2 inch represents 75 miles and the distance is 3 1/4 inches you need to mulitply 75 X 6 = 450 and then divide 75/2=37.5 then add the two totals
450 + 37.5 = 487.5 miles
