Answer:
Area of the triangle covered by the cars = 910.45 square km
Step-by-step explanation:
Since, all the sides of triangle ABC are given,
And formula for the area of a triangle with all sides given is,
Area =
Here, s =
And a, b, c are the measures of the sides of the triangle.
If a = 39 km, b = 87 km and c = 58 km
s =
s = 92
Therefore, (s - a) = 92 - 39
= 53
(s - b) = 92 - 87
= 5
(s - c) = 92 - 58
= 34
Now area of the triangle ABC =
=
= 910.45 km²
Area of the triangle covered by the cars = 910.45 square km
<span>k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
this means, </span><span>(k/-4) x -4 = - 0.8</span> x -4
this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
so k= 3.2
your answer is D
Is it a true or false answer? If it is then the answer would be false because the left side 0 does not equal to the right side 37,which means the given statement would be false
