<span>First, group the x values together (on one side) and the other values on the other.
6x + 3 - 1/2 x = -2x +5
6x - 1/2 x + 2x = 5 - 3
Now solve!
7 and 1/2 x = 2
x = 8
Hope this helps!</span>
Answer:
9.4 units
Step-by-step explanation:
Step one:
given data'
We are given the coordinates
x1=4.2
x2=-5.2
y1=-2
y2=-2
Required
The distance between the points
Step two:
The expression for the distance is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-5.2-4.2)²+(-2+2)²)
d=√((-9.4)²
d= √88.36
d= 9.4 units
You use long division when you divide polynomial by other polynomials. You use synthetic division to divide polynomials by binomials of the form (x-k).
Answer:

Step-by-step explanation:
we have the options

the one that is a perfect equare tinomial is:

because we can rewrite this as follows:
this is because we know that

thus

and the other options cannot be represented as a perfect square trinomial, so the correct answer is:

= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
