Step-by-step explanation:
a)
Twice of a number added to 5.
Let the number be n.
Twice of the number: 2n
Twice of the number added to 5: [tex]2n+5[/tex]
b)
Difference of squares of m and n multiplied by 6.
Difference of squares: [tex]m^{2} -n^{2}[/tex]
Difference of squares multiplied by 6: [tex]6(m^{2} -n^{2} )[/tex]
c)
r cubed minus y squared
r cubed: [tex]r^{3}[/tex]
y squared: [tex]y^{2}[/tex]
r cubed minus y squared: [tex]r^{3} -y^{2}[/tex]
d)
Five times of x raised to the power of 5 added to twice of y cubed
Five times of x raised to the power of 5: [tex]5x^{5}[/tex]
Twice of y cubed: [tex]2y^{3}[/tex]
Five times of x raised to the power of 5 added to twice of y cubed:
[tex]5x^{5} +2y^{3}[/tex]
