Step-by-step explanation:
15 r blue marbles
20- 5 = 15
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Yes it is not because 40 thousand + 5 thousand = 90,000 which is close to her goal
<span>y=x^2+5x+6
y=4x+12
Solution = (-3,0) and (2,20)
</span><span>y=x^2-3x-1
y=8x-1
Solution = (0,-1) and (11,87)</span>
<span>8-(-5)-4 (-7)
=8+5-4-7
=2</span>
