Answer:
I feel you ill try and help give me a sec
Step-by-step explanation:
Answer:
first the triangle
t area=b x h ÷2
=(5ft x 10.5ft)÷2
=26.25ft sq unit
second the rectangle
r area=L × b
=9ft × 7.5ft
=67.5ft sq unit
last the triangle
t area= b×h÷2
=(9ft×4.5ft)÷2
=20.25ft sq unit
<h3><u>Total</u><u> </u><u>area</u><u>=</u><u> </u><u>26.25ft</u><u>+</u><u>65.5ft</u><u>+</u><u>20.25ft</u></h3><h3><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>=</u><u>112ft</u><u> </u><u>sq</u><u> </u><u>unit</u></h3>
I think it’s -1 because with rise/run it goes down 2 and over 2 but the line is going down, so it’s negative.
Looking at choices A and B, we know that choice A would be $3.65/gallon because 21.90/6 is 3.65. Looking at the graph, we see that choice B is $2.75/gallon.
Choice B would be $.90 cheaper, so it would be the better option.
