The answer is a 20.
you do 20 * 15 = 300
700-300 = 400 divide by 10 which is 40
20(x) + 40(y) equals 60
If those are your roots, in factorization form they are [x-(-1+i)][x-(-1-i)], which simplifies to (x+1-i)(x+1+i). FOIL that out like you would anything else to get the mess that looks like this:
. Putting things in order makes it easier to deal with.
. Canceling out what we can, gives us
.
. That simplifies to
, which of course gives us
and
is the final result. Your missing term there is 2x

➷ Due to the corresponding angle rule, the top right angle of the quadrilateral would equal 98 degrees.
Angles on a straight line equal 180 degrees therefore, we can calculate the bottom right angle of the triangle
180 - 98 = 82 degrees
The bottom left angle of the triangle would equal 85 degrees as vertically opposite angles are equal
Angles in a triangle equal 180 degrees so we can now calculate x
180 - (82 + 85) = 13
The answer is 13 degrees
