-2y =-6x-8
y = 3x+4
y= 3x+4</span>
y-2 = 38
parallel side have the same length in a parallelogram
add 2 to each side
y =40
17 = x+3
parallel side have the same length in a parallelogram
subtract 3 from each side
14 =x
opposite angles are equal in a parallelogram
124 = 2u
divide by 2
u = 63
angles on the same side add to 180
124+ v-3 =180
121+v=180
v = 59
1/2a - 7 + 1/2a = 1/3
1/2a + 1/2a = 1/3 + 7
2/2a = (1 + 21)/3
a = 22/3
You have to distribute 3x+1 over the other parentheses
3x(2x^2 +4x-3) + 1• ( 2x^2 +4x-3)=
6x^3 +12x^2 -9x + 2x^2 +4x-3 =
Combine like terms
6x^3 +14x^2 -5x -3
