Answer:
The answer is 10x² - 4x.
Step-by-step explanation:
You have to apply Distributive Law,

So for this question :



In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25
in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10
The answer will be B because all three angles of the triangles add up to180 degrees, and we already know the total of two other angles are 100 degrees, which made the unknown angles have 80 degrees. Hope it help!
Do the indicated mult. first:
7v - 2v + 16 = 5v + 20
5v + = 5v +20. This is never true. NO solution.
