Choose the correct simplification of the expression (−2x + 6y)(4x − 6y). 8x^2 + 36xy − 36y^2 −8x^2 − 36xy + 36y^2 −8x^2 + 36xy − 36y^2 −8x^2 + 12xy − 36y^2

Step-by-step explanation:

(−2x + 6y)(4x − 6y)

To multiply this we use FOIL method

first we multiply -2x with 4x, it becomes -8x^2

Then multiply -2x with -6y, we get 12xy

multiply 6y with 4x, we get 24xy

multiply +6y with -6y, we get -36y^2

Now we commbine all the answers we got

combien like terms

12xy+24xy= 36xy

450 is the final answer! : )

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
