Like terms are similar in exponents.
12x^2 can be combined with -3x^2
9x^3 with -5x^3
-8x^4 is on its own
Final=
-8x^4 + 4x^3 + 4x^2
Since it’s a trapezoid, 111 + b will equal 180, as will 41 + a.
111 + b = 180 means b = 69.
41 + a = 180 means a = 139.
This happens simply because two angles that are positioned that way between parallel lines will always be supplementary. It’s also worth noting that all angles in any quadrilateral will add up to be 360 degrees.
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 2y = 12 ( subtract 3x from both sides )
2y = - 3x + 12 ( divide all terms by 2 )
y = - x + 6 ← in slope- intercept form
with slope m = -
