Step-by-step explanation:
(-0.4)×(-2)+(-0.4)×(-9)
formula for distributive property is if
A(B+C)
=A×B + A×C
=(8)(3.4)+13.812
=27.2 + 13.812
=41.012
the Answer is 41.012
Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
is equal to
, because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know
is just equal to 25, which means the simplified version of
is
.
Then we can use this new representation to finish solving.
, so the answer would be B
