<span>ABCD is an isosceles trapezoid with legs AB and CD
∴ AB = CD
</span>
<span>AB = 6y +5
</span>
<span>CD= 2y +1
∴ 6y + 5 = 2y + 1
6y - 2y = 5 - 1
4y = 4
∴ y = 4/4 = 1

Answer:
b) 4
Step-by-step explanation:
4 is the solution. There is more than one way to solve this problem. The easiest way may be to check each choice. Plug in each choice for day 4 and solve for the mean absolute deviation.
3t-18t+4=-26
first you want to move the 4 to the other side of the equation so subtract that from both sides of the equation which gives you this 3t-18t=-30.
Next you would combine the like terms that are on the left side of the equation giving you -15t=-30. Now you want t by itself so you divide both sides by -15 which would give you t=2
1A.) Cannot Be Factored
2B.) 7n(2n + 7 + n)
3C.) (b+3) (2b + 5)
4D.) -(xy - 2x + 12)
5E.) (r-5)(7r^2+6)
