Answer:
The correct answer is option B.
Step-by-step explanation:
The given rational expression is:
Factor the numerator and the denominator:
Factor the numerator using difference of two squares and the denominator using factorization by grouping.
This function is defined if and only if the denominator is not zero.
That is: (x+3)(x+2)≠0.
x≠-2,x≠-3
We simplify now to obtain:
The correct choice is the second option.
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
Let, that number = x
It would be: x * 25% = 21
x * 0.25 = 21
x = 21 / 0.25
x = 84
In short, Your Answer would be 84
Hope this helps!
4+5x=1
subtract 4 from each side
5x=-3
divide both sides by 5
x = -3/5
Step-by-step explanation:
(x+2y)(x-2y)
- x^2-2xy+2xy-(2y)^2
- x^2-4y^2
