25
The triangle given by 9, unknown, and 15 and the triangle given by 15, unknown, and x are similar triangles and therefore 9:15 = 15:x
X is 25 in this case
13 times 6 times 2.5 equals 195 square inches
Y = -3x + b
Plug in point
-4 = -3(3) + b
-4 = -9 + b, b = 5
Solution: y = -3x + 5
Yup it has to be a greater divedend if not answer would be completly wrong
It would be 3 and 1 one hundredth.
