So, x = 13, x = √3 and x =7i.
now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.
now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.
Answer:
R = (- 3.5, - 7 )
Step-by-step explanation:
Using the Section formula
= 
= 
= 
= - 3.5
= 
= 
= 
= - 7
Thus coordinates of R = (- 3.5, - 7 )
Answer:x= -3/8
Step-by-step explanation:
Area= a*height
the formula for an isosceles trapezoid is 1/2(base1+base2)*height. 1/2 base 2 and 2a will simplify to a base length of a. a times height or a*height
Answer:
Step-by-step explanation:
We know that tan(x) is defined as sin(x)/cos(x):
1/0 is undefined as 0 is in the denominator
