Answer:
x=5, -1
Step-by-step explanation:
I think you mean 2x^2-8x-10=0
2x^2-8x-10=0
Factor out a 2 (0/2 is still 0)
2(x^2-4x-5)=0
Divide by 2
x^2-4x-5=0
Find something that MULTIPLIES to get -5 and ADDS up to get -4, then factor
(x-5)(x+1)=0
Make each set =0
x-5=0
x+1=0
x=5, -1
Find the area of all the sides and then divide each area by two. add them all up to get your answer.
To find the area you would had to do a an triangle formula so the final answer would be 63 inches
