Answer:
15
Step-by-step explanation:
The formula for factoring a sum of cubes is:

We have a=3f and b=5g here.
So a*b in this case is 3f*5g=15fg.
The ? is 15.
-(3x-2)=-4(x+1)-4
-3x+2=-4x-4-4
-3x+4x=-4-4-2
x=-10
I think the answer is -1=x-3<4
Answer:
60°
please look into the solution down here.
Step-by-step explanation:
since BD bisects it, then the angles should be bisected symmetrically, or in other words, ANGLE ABD = angle DBC,
hence,
4x = 2x +30
2x = 30
x = 15
therefore, angle DBC = 2x + 30 = 2(15) + 30 = 60°.
