Answer:

\huge{\boxed{\sf{ 2y^{2} - 9 }}}

Step-by-step explanation:

( - 3y^{2} - 8 ) - ( - 5y^{2}+ 1 )

While subtracting , sign of each term of the second expression changes.

⇒- 3y^{2} - 8 + 5y^{2} - 1

Combine like terms : -3y^{2} and 5y^{2}

Like terms are those which have the same base.

⇒2y^{2} - 8 - 1

Remember : The negative integers are always added but posses the negative ( - ) sign.

⇒2y^{2} - 9

Hope I helped!

Best regards !

JL is a common tangent to circles M and K at point J. If angle MLK measures 61ᵒ, what is the length of radius MJ? Round to the n
Dvinal [7]
In the problem of insufficient data quantities. I can get a general  solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.

Let angle JLK like X.

So, angle JLM=61-x.

And it's mean that by using right triangle trigonometry 

Radius MJ = LM*cos(61-X)
