Answer:
a x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
Answer:
-200
Step-by-step explanation:
We are given that:
Simply insert this values into their correspondents in the equation given.
(-5 + (-15)) * (-5 - (-15))
Subtracting two negatives is like adding a positive and a negative.
(-5 + (-15)) * (-5 + 15)
Solve inside the parenthesis.
(-20) * (10)
Multiply.
-200
