x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
(3x + 3 + 4x + 2) = 13
(7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
22 and 22
step-by-step explanation:
10 plus 12 equals 22.
12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
f(x) = x^3 -2x^2 -3x
x( x^2 -2x-3)
x( x^2 +x -3x -3)
x( x(x+1) -3(x+1))
x( x-3)( x+1)
so zeroes are 0, 3,-1
