Answer:
=14.69km²
Step-by-step explanation:
We can use the Hero's formula to calculate the area
A= √(s(s-a)(s-b)(s-c))
s is obtained by adding the lengths of the three sides of the triangle and then dividing by 2, a, b and c are the ides of the triangle.
S=(5+6+7)/2
=9
A=√(9(9-6)(9-5)(9-7))
=√(9×3×4×2)
=√216
=14.69km²
Fraction of his error= 87.50/ $125
=0.7
Percentage= 0.7 * 100
= 70%
Answer:
-60x
Step-by-step explanation:
We simply open up the bracket and collect similar terms
So we have;
4(-15x-2) + 8 as:
4(-15x) -2(4) + 8
-60x -8 + 8
= -60x
