180
Step-by-step explanation:
draw it out it is a rectangle with length=15 and width = 12.
Area of a rectangle = LxW
=15x12
=180
(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply
(4a - 3)(a + 1) = 39(3b + 1)
4a^2 + a - 3 = 117b + 39
4a^2 + a - 42 = 117b
b =
