The area of a trapezium shaped field is 480m^2,the distance between two parallel
sides 15 m and one of the parallel sides is 20m . find the other parallel side
i will mark as brain lies

Area of trapezium = 1/2 * h (a+b)

here, 480= 1/2 *15*(20+b)

(20+b)=960/15

or, b=64-20

therefore, b= 44

Hope u got it...xd

x=30

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
