There is an infinite amount of 10 digits numbers with at leas two 1s in it.
Inequality that represents the lengths of the glass:
12 cm < x ≤ 12.2 cm
Answer:
1 is A 2 IS 1/8 3 IS B= 30
Step-by-step explanation:
Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.
