Which expressionis equal to (-7x+5.+5.3y)
a.-11x+2.8y
b.7x+2.8y
c.2x-0.2y
d.11x+13.4y

The simplified expression for the given expression will be:

c.

Step-by-step explanation:

Given expression:

To simplify the expression.

Solution:

In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.

This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.

So, we have:

⇒

Combining like terms

⇒

The like terms can be evaluated as

Thus, the simplified expression will be:

⇒  

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
