This is probably way overcomplicated but i cant remember how to do it
w = n
l = 2n+1
w*l = 66
n(2n+1) = 66
2n^2 + n =66
2n^2 + n - 66 = 0
using quadratic equation
n = 11/2
width = 11/2 = 5.5
length = 11 + 1 = 12

Answer:
F. not enough information
Step-by-step explanation:
there are no markings as to the lengths and there is no way of knowing
<span>The equation of a circle is (x-a)</span>²+(y-b)²=R²
(x-4)²+(y-0)²=(2√3)²
(x-4)²+y²=12
Answer:
75
Step-by-step explanation:
Let x represent the 5th score. Then:
70 + 80 + 85 + 90 + x
---------------------------------- = 80
5
Then:
150 + 175 + x 325 + x
-------------------- = 80 => ------------- = 80
5 5
so that: 325 + x = 400
Thus, x = 75.
If Josh earns a 75 on his 5th quiz, his 5-quiz average will be 80.
