Which expression is equivalent to 9 x squared minus 2 y + 3 x squared minus 3 y? 6 x squared minus y + 6 x squared minus 5 y
6 x squared minus y + 3 x squared minus 4 y
10 x squared minus 4 y + 2 x squared minus y
11 x squared + 2 y + x squared minus 3 y

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2
