Area of triangle = base x height x 1/2
Area of the triangle:
= 12 x 15 x 1/2
= 180 x 1/2
= 90 units^2

Answer:
43 m/hr
Step-by-step explanation:
258m/6hr = 43m/hr
distance over time
Let's simplify first:
4ax+12-3ax=25+3a
ax+12=25+3a
ax-3a=25-12
a(x-3)=13
That is how far you can take it, unless there were some additional information for this question.
