1. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd
a^2b^2+8ab−9ab−72
2. Collect the like terms
a^2b^2+(8ab−9ab)−72
3. Simplify
a^2b^2-ab-72
Hope this helps
Answer:
4x ≤ 30
Step-by-step explanation:
Omar gets 30 dollars off because $25 + $5 = 30. Let x = pairs of socks
We know each pair costs $4, so the cost would be 4x. Omar has to buy as many pairs as he can with only the coupon and gift card. Omar has to spend $30 (the full discount) or less than $30. Therefore, the inequality would be: 4x ≤ 30 or 4x is less than or equal to 30 ($30).
Answer:
d
Step-by-step explanation:
the graph increases then goes horizontal
140 divided by 14 is 10. So x is 10. And Y is 140. 140 divided by y (1) =140
Now, we know that 90°< θ <180°, that simply means the angle θ is in the II quadrant, where sine is positive and cosine is negative.
