Answer:
4/2=2
Step-by-step explanation:
When determining the slope of a line from a graph, slope is rise over run. Your line rises 4 points and then runs 2 points from point a to point b.
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

To find the area of a triangle, you need the formula . A= b*h divided by 2
Answer:
i have written it in copy
hope it helps.
Step-by-step explanation:
i wrote it just for you so please review me if it is right or wrong and comment me if you're still confused!!
X = 4
7(4)+14-3(4)=30
7(-11)+14-3(-11)=-30
So, 4 is the answer because when substituted for X, it gives you 30.
