You just add them together-
Answer:
The side length required is 15 inch.
Step-by-step explanation:
volume = L*b*h
height = 2 inch
side length = x
The box used is square prisms so, side length = width = x
Now, using the formula for volume:
V = L* b* h
or, 450 = x* x * 2
or, 450 = 2x²
or, 225 = x²
∴ x = 15 inch
So the length required is 15 inch.
Answer:
x = 4
y = 10
Step-by-step explanation:
3x + 2y = 32 (Multiply this equation by -3)
9x - 3y = 6
-9x - 6y = -96
9x - 3y = 6
-9y = -90
y = 10
3x + 2y = 32
3x + 2(10) = 32
3x + 20 = 32
3x = 32 - 20
3x = 12
x = 4
Answer:
8( 3x+2y) ( 9x^2 -6xy +4y^2)
Step-by-step explanation:
216x^3 + 64y^3
Factor out the greatest common factor of 8
8( 27x^3 +8y^3)
Rewriting
8 ( (3x)^3 + (2y)^2))
Recognizing this as the difference of cubes)
a^3 + b^3 = (a+b) (a^2-ab+b^2)
8 ( (3x)^3 + (2y)^2)) = 8( 3x+2y) ( 9x^2 -(3x)(2y) +4y^2)
=8( 3x+2y) ( 9x^2 -6xy +4y^2)
