Answer: angle 2 is acute
Step-by-step explanation: the angle is less that 90⁰
Unit rate means how much does it cost for 1 unit
140 for 18ft^2
divide by 18
140/18=7.77777777777777
so the unit rate is $7.78 per square foot

Answer:
![Length=27feet\\Width=12 feet](https://tex.z-dn.net/?f=Length%3D27feet%5C%5CWidth%3D12%20feet)
Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3
![L=(2W+3) feet\\\\](https://tex.z-dn.net/?f=L%3D%282W%2B3%29%20feet%5C%5C%5C%5C)
Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width
![90=(2W+3)*W\\\\2W^2+3W=90\\\\2W^2+3W-90=0\\\\](https://tex.z-dn.net/?f=90%3D%282W%2B3%29%2AW%5C%5C%5C%5C2W%5E2%2B3W%3D90%5C%5C%5C%5C2W%5E2%2B3W-90%3D0%5C%5C%5C%5C)
Using Factorization Method to solve quadratic equation:
![2W^2-12W+15W-90=0](https://tex.z-dn.net/?f=2W%5E2-12W%2B15W-90%3D0)
Taking common from the equation:
![2W(W-12)+15(W-12)=90\\\\(W-12)(2W+15)=0\\\\W-12=0\\\\W=12 feet](https://tex.z-dn.net/?f=2W%28W-12%29%2B15%28W-12%29%3D90%5C%5C%5C%5C%28W-12%29%282W%2B15%29%3D0%5C%5C%5C%5CW-12%3D0%5C%5C%5C%5CW%3D12%20feet)
OR
![2W+15=0\\\\2W=-15\\\\W=-7.5 feet](https://tex.z-dn.net/?f=2W%2B15%3D0%5C%5C%5C%5C2W%3D-15%5C%5C%5C%5CW%3D-7.5%20feet)
The Width cannot be negative, therefore Width(W)=12 feet
![Length=2*Width+3\\\\=(12*2)+3\\\\=24+3\\\\=27 feet](https://tex.z-dn.net/?f=Length%3D2%2AWidth%2B3%5C%5C%5C%5C%3D%2812%2A2%29%2B3%5C%5C%5C%5C%3D24%2B3%5C%5C%5C%5C%3D27%20feet)
![Length=27feet\\Width=12 feet](https://tex.z-dn.net/?f=Length%3D27feet%5C%5CWidth%3D12%20feet)
