Area of triangle is
A=b•h/2
A=(10x+5)(2x-5)/2
A=20x^2-50x+10x-25/2
A=20x^2-40x-25/2
A=2(10x^2-20x-12.5)/2
cancel 2 in numerator and denominator
A=10x^2-20x-12.5 in^2
Hope this helps
Answer:
44ft
Step-by-step explanation:
To find the answer, you need to first break down your shape. We can see that the 2 sides are identical so we can just multiply the area of on eof the sides by 2. The 2 sides equal 20 in all. Now lets look at the last section. To find an unknown side, we need to subract the 2 known sides. 8-5=3. 3x8=24
24+20=44
Hope this helps.

Answer:
28.6
Step-by-step explanation:
Pathagorem therom
We have to choose two points of this graph:
A(5,0)
B(0,-4)
And we have to compute the slope:
Given two points A(x₁,y₁) and B(x₂,y₂) the slope between these points would be:
m= slope
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(-4-0)/(0-5)=-4/(-5)=4/5
Answer: the slope would be 4/5 and all of these answer would be wrong.
