The correct answer is D. 36 x 1/9
When there is a negative exponent on a whole number:
4 ^-2
1/ 4 ^2 = 1b16
36.00 will be enough to pay for fuel because if you multiply the 8.8 gallons of diesel needed by the fuel cost per gallon you get 35.112
Positive 28 because to negative will equal a positive number
You would use the method:
c. SSS
That is because since you were not given any angles and only sides of the window you could only prove this with three different sides.
Start with 6x + 2y = 15. Then subtract 6x + 2y from both sides. The left side of your equation then becomes 0 and the right side 15 - 6x - 2y.
