Answer:
X=60
Step-by-step explanation:
Sum of the Quadrilateral interior angles:360
360-70-130-100=60
Step-by-step explanation:
x^2 -2kx +7k -12 = 0
two equal roots -->Δ = b^2 -4ac = 4k^2 - 4(7k-12)=0 = 4(k^2 - 7k +12)=4(k-4)(k-3)=0
so k =3 and k =4
It's really simple
if a+95=180 you solve for a
a+95=180
-95 -95
a=85
a triangle in total is 180 degrees
now that you know two of the angles find x is really easy
you add 60+85
you get 145
you then subtract 180-145
and get 35 as the answer
x=35
The answer is b because the slope is rise over run it goes up 2 times and right 4 times which are both positive so the answer is 2/4 or 1/2
roots of a polynomial are (x-c1)(x-c2)(x-c3) .......(x-cn). Basically, plug every root you have into a (x-__) and then multiply them all together. Just be careful of signs. If your root is positive, it is written as (x-__). If your root is negative, it is written (x+__)
