Answer:

1: n > -75

2: n < -12

Step-by-step explanation:

1: n/-3 - 8 < 17

n/-3 (- 8 + 8) < 17 + 8

n/-3 < 25

n/-3(-3) < 25(-3)

n < -75

n > -75 (switch symbol when you divide or multiply by a negative number)

2: n/-2 + 11 > 17

n/-2 (+ 11 - 11) > 17 - 11

n/-2 > 6

n/-2(-2) > 6(-2)

n > -12

n < -12 (switch symbol when you divide or multiply by a negative number)

These circles are tangent .

Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.

According to the question

These circles are :

A > Concentric

This option is incorrect because circle are concentric if and only if they have common center .

B> none of these

This option is incorrect .

C > Tangent

This option is correct as Two circles are tangent to each other if they have only one common point and in the figure there is only one common point between both circles .

D> Congruent

This option is incorrect as this two circles have different size but in congruent both circle should be same size which is not possible here.

Hence, These circles are tangent .
