Answer:
15.6
Step-by-step explanation:
the traingle is right so u have to apply the pythagorean theorem to find x so x^2=10^2+12^2=244
so x=15.6
Answer:

Answer:
Your given polynomial has only one real root which is x= -4
Step-by-step explanation:
find any zero of the polynomial.
x-a divides the polynomial where a is a zero of polynomial:
So x+4 divides
If we factor out a two, we can use the quadratic formula.
2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i) or (3-i)/2 .
Final answer:
then x=-4, (3+i)/2, or (3-i)/2
Answer:
y - 5 = (3/2)(x - 2)
Step-by-step explanation:
If two lines are perpendicular, their slopes are negative reciprocals of one another.
The slope of 2x + 3y = 5 is found by solving this equation for y:
3y = -2x + 5, or y = (-2/3)x + 5/3.
Thus, the slope of the new line is the negative reciprocal of -2/3, which in turn comes out to 3/2.
Use the point-slope formula y - k = m(x - h):
Substituting the givens, we get y - 5 = (3/2)(x - 2)
Ab+ac=a(b+c)
a is common factor
factor
6ab=2*3*a*b
9bc=3*3*b*c
common factor is 3*b or 3b
3b(2a)+3b(3c)=3b(2a+3c)
