Answer:
18
Step-by-step explanation: take 6 times q(3) which gives you 18, then you add 8 and subtract 8
Step-by-step explanation:
6q+m-m subsitute the variables
6(3) + 8 - 8 cancel out 8-8 bc now its 0
6(3) multiply
18 is the answer
28m+4n-12m+3
28m-12m+4n+3
16m+4n+3
a*2+b*2+c*2+d
If i's meant to be Pythagorean theorem, a*a+b*b=c*c
B is the answer
