Another expression would be D) 2x+10
Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so
50*4*10*100=200*1,000= 200, 000

x-y+xy=1-1+1*1=0+1=1
AX=XF
4y+3=2y+7
4y-2y=7-3
2y=4
y=2
then,
AX=4y+3
=4×2+3
=8+3
=11
