Answer: think of your problem as Ax +By=C. You get your x intercept and y intercept by c divided by A and c divided by B. Put the y intercept on the y axis and x intercept on the x axis
Answer:
4x² -4xy -4y -4
Step-by-step explanation:
In this case, a= 2x -y and b= y +2.
(2x -y)² -(y +2)²
= (2x -y +y +2)[2x -y -(y +2)]
= (2x +2)(2x -y -y -2)
= (2x +2)(2x -2y -2)
= 2x(2x) +2x(-2y) +2x(-2) +2(2x) +2(-2y) +2(-2) <em>(expand)</em>
= 4x² -4xy -4x +4x -4y -4
= 4x² -4xy -4y -4
Alternatively, start by expanding the brackets.
(2x -y)² -(y +2)²
= 4x² -4xy +y² -(y² +4y +4)
= 4x² -4xy +y² -y² -4y -4 <em>(</em><em>expand</em><em>)</em>
= 4x² -4xy -4y -4 <em>(</em><em>simplify</em><em>)</em>
Answer:
multiply lenght x width x height and multiply by 2 that should get you 392
Step-by-step explanation:
Answer:
D (point Y, ray YZ, angle XYZ)
Step-by-step explanation:
--> a point is just one letter, it cannot be more than one because more than one indicates a connection between 2+ points.
--> a ray is only 2 points/letters, unless the letters are all on one line. the ray is 2 points because it indicates a connection between point Y and point Z.
--> an angle should be 3 letters, and the letter in the middle (in XYZ it's Y) is the point where the angle "occurs" or closed at
Hope this helps!
-8 and 5: -8 x 5 = -40; -8 + 5 = -3
