-4xy^6 * -3x = 12x^2y^6
-4xy^6 * 2y = -8xy^7
6 * -3x = -18x
6 * 2y = 12y
Answer = 12x^2y^6 + -8xy^7 + -18x + 12y
Area: 9•6= 54ft sq Perimeter 9+9+6+6= 30ft
Answer:
34.29 Inch.
Step-by-step explanation:
The Aspect Ratio of a screen is the ratio of the Width to the Height of the screen.
We are told that the TV screen has an aspect ratio of 21:9
Therefore:
The height of the TV will be approximately 34.29 Inch.
Remember for this type of question.I'm guessing you make the equation equal to 0. Then square both sides the (X ^2-16) and 0. Then the square root goes away. Then you factor it according to the difference of squares method. By taking the square root of x^2 and 16. So ultimately it turns into 2 binomials according to the difference of squares method. The simplified answer would be (X-4)(X+4)=0. To solve for x in each case, take each respective equation separately and make it equal to 0. Solve for x.
Answer:
Answer:
11+ 9 = 20
Step-by-step explanation:
=> 21-9=11
21 - 9 equals to 11 is actually a wrong answer
So in order to find the subtraction problem that will help us truly know whether the equation is wrong
=> 11+ 9 = 20
OR THE SECOND EQUATION IS
=> 21 - 11 = 10
