A Forestry service biologist has time to study insect infestation in an area or so square kilometers on the forest service map the scales
1 centimeter quote 1 kilometer. The four possible sector available for
study appear as rectangles on the map. Complete the table by
calculating the map area of each sector
2
Sector Map Dimensions (cm) Map Area ( cm )
A 2.5 5.8
B 3.7 2.1
C 4.7 3.5
D 4.2 x 2.8
a. How can you calculate the actual area of each sector?
b. Does the biologist have time to study all four areas? Explain why or why not?
c. What combinations of three sectors could the scientist study?
d. Which combination of sectors maximizes the area to be studied?
Explain why.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i believe it's a.

i'm not sure on this one, most likely correct.

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
