Answer:
3
+2xy+6xy+12x+4y
Step-by-step explanation:
(3x+y)(x2+2y+4=+2xy+6xy+12x+4y
Answer:
Not sure if this is correct but it should be y=210x-140
Step-by-step explanation:
First you have multiply 6 by both 3x and 8
6*3x = 18x
6*8= 48
18x + 48 + 32 + 12x
now combine like terms
18x + 12x = 30x
48 + 32 = 80
so 30x + 80 is your answer
5% of $50 = 5/100 x 50 = $2.50
Total = 50 + 2.50 = $52.50
The saes tax is $2.50; her total cost of the shirt is $52.50
