1 answer:

5 0

$(x^2+3y-3) - (-2x^2+3y-1)$
Apply plus/minus rule.
-(-a)=a amd -(a)=-a
$(x^2+3y-3) - (-2x^2+3y-1)=x^2+3y-3+2x^2-3y+1
$
$=x^2+3y-3+2x^2-3y+1 \\
Add \ like \ terms \\
=3x^2 - 2 \\$
$Answer: \ 3x^2-2$

Evgen [1.6K]

Answer:

$(B)r=\dfrac{85}{12}$

Step-by-step explanation:

Given a circle centre J

Let the radius of the circle =r

LK is tangent to circle J at point K

From the diagram attached

LX=6
Radius, XJ=JK=r
LK=11

Theorem: The angle between a tangent and a radius is 90 degrees.

By the theorem above, Triangle JLK forms a right triangle with LJ as the hypotenuse.

Using Pythagoras Theorem:

$(6+r)^2=r^2+11^2\\(6+r)(6+r)=r^2+121\\36+6r+6r+r^2=r^2+121\\12r=121-36\\12r=85\\r=\dfrac{85}{12}$

The length of the radius, $r=\dfrac{85}{12}$
