Answer:
28800 square feet
Step-by-step explanation:
We solve this using the Heron's formula
Area of a Triangle = √s(s - a)(s - b)(s - c)
s = a + b + c/2
s = 100 + 580 + 600/2 = 640
Area of the land(Triangle) = √640 × (640 - 100)(640 - 580)(640 - 600)
= √640 × (540) ×( 60) × (40)
= √(829440000)
= 28800 square feet
Therefore, the approximate the area of the land is 28800 square feet.

Answer:
(x) = x - 3
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x + 3 (subtract 3 from both sides )
y - 3 = x
Change y back into terms of x with x = (x) , thus
(x) = x - 3
Answer:
28 polio vaccinations and 32 measles vacinnacions.
Step-by-step explanation:
x= polio vaccinations
y= measles vaccinations
here we have an ecuation system:
x+y=60 (vaccinations)
2x+4y=184 (doses)
In order to solve it I will solve the x in the first ecuation:
x=60-y
And replace it on the other ecuation:
2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32
Now I replace this result in x=60-y, so x=28.
