Answer:
19.81cm^2
Step-by-step explanation:
To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:
sqrt(p*(p-a)*(p-b)*(p-c))
Plugging the values into this formula gives 19.81cm^2.
Answer:
The value of the expression is - 5.
Step-by-step explanation:
(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=
-2x+10+6x-5y-12+x+8y-16=
(-2x+6x+x)+(-5y+8y)+(10-12-16)=
5x+3y-18
if x=5 and y=-4 then
5*5+3*(-4)-18=25-12-18=25-30=-5
Answer:
2904
Step-by-step explanation:
Answer: The average change in field position on each run was 
yards.
Step-by-step explanation:
