First, you should substitute a, b, and c with -3, 9, and 4, so you get 4(-3(2)+9+4)
Next, following PEMDAS, you solve everything in the (,), leaving you with 4(7).
Lastly, your answer is 28.
Answer:
No
Step-by-step explanation:
24 over 40
24/40 = 3/5
divide both numbers by 8 to find the proportion
3/5 does not equal 4/5
3/4x=15 you flip 3/4 to 4/3 and cancel it out on one side leaving x by itself then you multiply 4/3 by 15 and you get 60/3 and that equals 20 x=20
