Answer:
17x^2+31x+3
Step-by-step explanation:
The volume of the first cube is (5h^2)^3, while the volume of the second cube is (3k)^3, so their total volume is (5h^2)^3 + (3k)^3. We can use the special formula for factoring a sum of two cubes:
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
(5h^2)^3 + (3k)^3 = (5h^2 + 3k)((5h^2)^2 - (5h^2)(3k) + (3k)^2)
= (5h^2 + 3k)(25h^4 - 15(h^2)(k) + 9k^2)
This is the second of the given choices.
Let's assume
length of rectangle is L
width of rectangle is W
the width of a rectangle is 3 meters more than one-fourth its length
so,

the perimeter is 10 meters more than twice its length
we know that
perimeter =2(L+W)
so, we get

now, we can simplify it

subtract both sides by 2L



now, we can find L

subtract both sides 3


multiply both sides by 4


so,
length of rectangle is 8 meter
width of rectangle is 5 meter ............Answer
