Answer:
16m^2-40mn+25n^2
Step-by-step explanation:
This is using (a-b)^2= a^2-2ab+b^2
Now if you replace a with 4m and b with 5n you will get 16m^2-40mn+25n^2
Your answer would be 4 :)
A 1/2 and 4/8 because to make them both have same denominator you multiply 1/2 by 2 and get 4/8 or you can do it the easy way and simpliphy 4/8 to 1/2. 4 is half of 8 so there for it would be 1/2.
Answer:
Step-by-step explanation:
multiply each variable's exponent by 2
(5x^2y^3)^2=5^2x^(2*2)y^(3*2)
simplify
5^2x^(2*2)y^(3*2)=25x^4y^6
Answer:
18.8
Step-by-step explanation:
the distance between E and F is 6
the distance between F and G is 5
the distance between E and G is 7.8102
add them all together to get 18.8102
