Answer:
2x+3y+5=0
a = 2 b = 3 c=5
Step-by-step explanation:
We are asked to express 2x+3y=-5 in the form ax+by+c=0
Add 5 to both sides
2x+3y+5=0
We can now find the values of a, b and c now that the equation is in standard form.

Answer:
63m^2
Step-by-step explanation:
Find the area of each base
2.5(10)= 25
1.5(10) = 15
2(10) = 20
Add them together
20 + 15 + 25 = 60
Now find the area of the triangles at each side
2(1.5)(1/2) = 1.5
Since there are two triangles, multiply the area by 2
1.5(2) = 3
Add the areas together
60 + 3 = 63
There's your answer
