In the adjoining figure O is the centre of the circle the tangent to the circle of radius 6 cm from the exterior point P of the
slamgirl [31]

Answer:

Let P be the external point. O be the origin. join O and P get OP and nearest point on the circle from P be A.

Let Q be the point onthe circle  in which, tangent make 90° with radius at Q.

PQ = 8 and OQ = 6

we get a right angled triangle  PQO right angled at Q.

so, OP^2 = OQ^2 + PQ^2= 8^2 + 6^2 = 64 + 36 =1==

therefore OP =10cm

we need nearest point from P, which is PA

PA = OP - OA= 10 -6=4cm

Sellus Evaluate the expression when m=25. m + 2(m-5) = [?]​
stiv31 [10]

Answer:

65

Step-by-step explanation:

So we have the expression:

m+2(m-5)

And we want to evaluate it for m=25.

So, substitute 25 for m:

=(25)+2((25)-5)

Subtract:

=25+2(20)

Multiply:

=25+40

Add:

=65

So, our answer is 65.

And we're done!

a+b=6

a-b =4

______subtract

(a-a)+(b-(-b))=6-4

0+2b = 2

b= 1

put the value of b at any equation

a+1 =6

then a=6-1=5

a square+b square= 25+1= 26
