Point d is the center of the inscribed circle of a abc. which step can you use to draw the inscribed circle of a abc?
a.
draw arcs of equal lengths intersecting ab. bc. and ac in two points each.
b. draw the perpendicular bisectors of ab bc. and ao that pass through point d.
c. label a point e on ab and draw a line joining e with d.
d. draw a line through d that is perpendicular to one of the sides, ab bc or ac.
o e.
draw one arc each on ab and bc, and find their point of intersection,

(x+3)(x+7)

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
