Since I do not have answer choices, I can conclude things that may or may not be an answer choice. Just from the problem, you can tell that Marie lost more weight, because 175 -150 = 25, while 190 - 180 = 10. Indirectly, you can say that she might have worked out more, or changed her diet, although that would merely be an inference. If you have answer choices please let me know and I can answer more. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine).
The sum of polynomials involves adding the polynomials
The other polynomial is 
The sum of the polynomials is given as:

One of the polynomials is given as:

Represent the other polynomial with Q.
So, we have:

Substitute the expressions for P and Sum

Make Q the subject

Evaluate like terms

Hence, the other polynomial is

Answer:
116
Step-by-step explanation:
《ANSWER》
《LINEAR EQUATIONS》
Solving all we get as
↪1) 5 (x -2) = 5x - 7
since after solving X is cancelled , NO SOLUTION
↪2) -3 (x - 4) = -3x + 12
SINCE after solving X is any value , infinitely many solutions
↪3) 4 (x + 1) = 3x + 4
solving we get as , 4x+ 4 = 3x + 4 =》 X =0
only one solution
↪4) -2 (x-3) = 2x - 6
Only one solution
↪5) 6 (x + 5) = 6x + 11
NO SOLUTION
All the equations are solved by the distributive law of algebra
Sum of linear pair of angles = 180°
so
<EFG + <GFH = 180°
2n + 21 + 4n + 15 = 180°
6n + 36 = 180°
6n = 144
n = 24
<EFG = 2(24) + 21 = 69°
<GFH = 4n + 15 = 4(24) + 15 = 111°
