b = -0.5 and a = 1. 2=3+-1. 1 to the third power is just 1, times 8 is 8. -0.5 to the third power is -0.125. -0.125 times 8 is -1. 8 - (-1) is 9. 36 times 1 is 36, times -0.5 is -18. 9-(-18) = 27. I hope this helps! Could I possibly get brainliest?
I am pretty sure 3 units is right
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
Answer:
I'll edit my answer when you give more context, but for now, say you knew the values of A and B. Say A is 3 and B is 13. In order to find out C you'll need to subtract A from B; 13-3=10. C=10 in this situation.
Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet
