Answer:

x =9

Step-by-step explanation:

A \cup B =29

-->A = 29 -17 = 12

-->B = 29 -21 = 8

x=A \cap B =A \cup B - A - B= 29 - 12 - 8 = 9

So to find x, you have to add both A and B which is 38. Since AuB (excluding the overlap) is 29, subtract 38 from 29 and you get 9 for x.

<span>F = 60.0N/cos30.0deg </span>
<span>F = 69.3 N
</span><span> Fy = Fsin30.0deg </span>
<span>Fy = 69.3 N sin 30.0 deg </span>

Find the value of y when x=3<br> y=2x3<br> y=0
MaRussiya [10]
Answer: 54

Why? You need to put 3 in for x so you get
2(3)^3
3 to the third power is 3*3*3 which equals 27
2(27)
Now you must do 2 times 27 and you get 54

Hope this helps
