Your answer would be -8 because your multiplying 4 times negative 2
Step 1. Apply FOIL method. bb+b*2+8b+8*2
Step 2. bb+2b+8b+8*2
Step 3. Add similar elements. bb+10b+8*2
Step 4. Apply exponent rule. b^2+10b+8*2
Step 5. Multiply the numbers. b^2+10b+16
b^2+10b+16 is your answer.
Answer: 200 adult tickets.
Step-by-step explanation: 500 ÷ 2 = 250
250 - 50 = 200
if you are still confused i can go into further detail:
because there were 50 more student tickets sold that means you would divide the total # of tickets sold to get 250 then you would subtract 50 from the adult tickets because there were 50 more student tickets than adult tickets.
Answer:
W = 7 - x
Step-by-step explanation:
The perimeter is P= 2L + 2×W , where L is the length and W is the width.
If L = (x+2) , replacing L with the expression x+2 we have
P= 2×(X+2) + 2W ⇔ 18 = 2x + 4 + 2W ⇔ 2W =18 - 2x - 4 ⇔ 2W = 14 - 2x
⇔ W = 7 - x
