Answer:
A or 3
Step-by-step explanation:
2/3+2/3=4/3 or 1 1/3
4/3+2/3= 6/3 or 2
4/7 for the 1st one., 8/9 for he 3rd dunno about middle one soz
I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.
My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
Step-by-step explanation: Notice that the two equations in this problem have the same slope of -1/4 but different y-intercepts.
When lines have the same slopes, they are parallel.
Parallel lines never meet/intersect so there is no solution.
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.
