Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
Answer:
2x^2 -8x
Step-by-step explanation:
2x(x-4)
Distribute the 2x
2x*x -2x*4
2x^2 -8x
For x, it would be
y = 2x - 5
+5 +5
y + 5 = 2x
2 2 2
y/2 + 5/2 = x
