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
A model shows the visualize of what you need to do in order to complete the problem your asked. It can also show important steps and make it easier for you to answer the question, like length×height×width.
Answer:
40w^3
Step-by-step explanation:
I'm assuming you meant w^3 (w to the third power). In that case, you would just add 34 + 13 + 11 - 18 because they are all like terms (coefficients of w^3).
Answer:
1.4000
2.5.551
3.6.8
4.10.00
5.4
Step-by-step explanation:
1 4066 as an example start from the end a 5 or more it turns to a zero and the one next to it
so in this case we now have 4100 but since it isn't 5 or more we make it a zero and move on so now we have 4000
sorry if I am wrong I am also an idiot so hopefully this helps for the future :)
