If E=[-1,0,1,2,3,4] and F=[3,4,5,6,7,8] what is E U F?
KatRina [158]
All elements from set E and from the set F. The same elements are only once.
Answer:
x = 67
Step-by-step explanation:
If the measure of the entire chord is 166°, then if you add the two angles that form it together, it will equal 166.
So,
x + 15 + x + 17 = 166
Simplify.
2x + 32 = 166
Subtract 32 from both sides.
2x = 134
Divide both sides by 2.
x = 67
I hope this helps! Feel free to ask any questions!
I don’t really know what you mean here but i guess you mean f(x)=2x+3=0
In that case:
F(x)=2x+3=0
Subtract 3 from both sides:
F(x)=2x=-3
Divide both sides by 2:
F(x)=x=-3/2.
Answer:
1. 2(a^2 + 3a + 9)
2. 5(x^2 - 1)
3. 3(t + 8)(t - 2)
4. n(4 - n)
Step-by-step explanation:
For 1, you can only factor out the constant from each.
For 2, you can also only factor out the constant, but remember that you include the 1 when dividing 5 by 5.
For 3, you can factor out the constant and the variables.
For 4, you can only factor out the variable.
