Answer:
(x+3)(x−7)
Step-by-step explanation:
Break the expression into groups.
=(X^2+3x)+(-7x-21)
Factor out x from x^2+3x: x(x+3)
Factor out -7 from -7x-21: -7(x+3)
=x(x+3)-7(x+3)
Factor out common term x+3
=(x+3)(x-7)

Answer:
Volume_stack = 214 n^3
Step-by-step explanation:
The volume of the stack is the sum of the volume of the two boxes
The rectangular box has a volume of
V_rectbox = long*wide*height
V_rectbox = 6 in * 5in * 5 in = 150 in^3
The volume of the cube is
V_cube = long*wide*height , but since all its sides are equal
V_cube = side^3 = (4 in)^3 = 64 in^3
Volume_stack = V_rectbox + V_cube = 150 in^3 + 64 in^3
Volume_stack = 214 n^3
Answer:
