B = 18 because 18-5 is equal to 3 and 3x3 is equal to 9.
The slope-intercept form:

m - slope
b - y-intercept
We have m = 2 and b = 3. Substitute:

The correct answer is 4> -3
Answer:
In quadrilateral ABCD we have
AC = AD
and AB being the bisector of ∠A.
Now, in ΔABC and ΔABD,
AC = AD
[Given]
AB = AB
[Common]
∠CAB = ∠DAB [∴ AB bisects ∠CAD]
∴ Using SAS criteria, we have
ΔABC ≌ ΔABD.
∴ Corresponding parts of congruent triangles (c.p.c.t) are equal.
∴ BC = BD.
