Answer:
Answer is 12 isnt it
Step-by-step explanation:
12×4=48
48+9=57
Use PEMDAS.
Parenthesis first.
(-15)-(-12)+3-(-9)
Next multiply,
(-15)+12+3+9 (two negatives get you a positive)
Finally, add and subtract:
-15+24=9
You get 9 as your answer.
Hope this helps!
MN + NP = MP
6x - 7 + 2x + 3 = 60
8x - 4 = 60
8x = 64
x = 8
MN = 6(8) - 7 = 56 - 7 = 49
answer
x = 8
MN = 49
Wrong , actually the complement of an obtuse angle is a right angle
