Answer:
( a+b) ( m^2 + n^2)
Step-by-step explanation:
factorise like terms
m^2 ( a + b ) + n^2 ( m^2 + n^2)
then put like terms together put remaining terms in a bracket
( a + b) ( m^2 + n^2 )

Answer:
The phones of the first group have is 11
The ipads the first group has is 6
Step-by-step explanation:
Assuming the number of phones the first group has is x while the number of the ipads the first group has is y.
x+y=17;2x+3y=40.
x+y=17
x+y+−y=17+−y(Add -y to both sides)
x=−y+17
2x+3y=40
2(−y+17)+3y=40
y+34=40(Simplify both sides of the equation)
y+34+−34=40+−34(Add -34 to both sides)
y=6
x=−y+17
x=−6+17
x=11(Simplify both sides of the equation)
x=11 and y=6
So the number of phones the first group have is 11 and the number of ipads the first group have is 6
