I can’t really see the equation, what’s the equation? You can only see the bottom of it
A)We have been given →
Hieght of trough = 5m
length of trough = 6m
Breadth of trough = 4m
so , As the top is opened for feeding animals.
Area of base = length× Breadth
= (6×4) m²
= 24 m²
Area of Front and back face = Hieght × length
= (5×6) m²
= 30m²
Area of side faces = hieght × Breadth
= (5×4) m²
= 20 m²
____________________________________
B)Total Surface area of trough will be given by formula - 2(lb+bh+hl)
= 2{(6×4)+(4×5)+(5×6)}
= 2{24+20+30}
= 2×74
= 148 m²
As we have been told top is open , so we will deduct top from Total surface Area to obtain Surface area →
(148-24) m²
(Area of top will be same as base area , that is 24m² as we have solved in A)
= 124m²
Answer→ Surface area of trough is 124m²

<span>Part A
</span>The variables would be x and y where as the coefficients would be 25 and 100
Part B
There are two terms in the expression, those being 25x and 100y. This is because s plus or minus sign separates terms, and in this case, we only have one plus sign.
<span>Part C
</span>The term that represents the total earnings from mowing lawns in 100y, because the prompt says that he earns $100 mowing lawns.
Answer:
3/4
Step-by-step explanation:
1/4 + 1/4 + 1/4 =3/4
or
1/4 x 3 = 3/4
