Here,

a-b=14

ab=8

<u>we</u><u> </u><u>know that</u><u>, </u>

\tt{(a-b)^2=a^2+b^2-2ab  } ⠀

<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>

\tt{ (14)^2=a^2+b^2-2×8 } ⠀

\tt{196=a^2+b^2-16  } ⠀

\tt{a^2+b^2=196-16  } ⠀

\tt{a^2+b^2=180  } ⠀

Answer:

\bold{ a^2+b^2=212} 

Step-by-step explanation:

a-b=1

ab=8

So,

\mapsto{a^2+b^2-2ab=(a-b)^2   }     

\mapsto{a^2+b^2-2×8=(14)^2   } 

\mapsto{a^2+b^2-16=196  } 

\mapsto{a^2+b^2=196+16  } 

\mapsto{a^2+b^2=212   }

In the transformation ABC A'B'C', the preimage of B' is ____. . a0
Misha Larkins [42]

Answer:

Pre image of B' is B

Step-by-step explanation:

Given:

ABC is a triangle

A transformation is done on ABC so that the image is A'B'C'.

Note that transformations are of various types such as dilation, vertical shift, horizontal shift, rotation about a point, reflection on a line, etc.

In any type of transformation, corresponding vertices will be matched.  In other words, A will become A', B will become B' and C will become C'.

Because of the property of the transformation to keep images similar and also transforming correspondingly the vertices we get preimage of B' would be nothing but B itself.

Solve for x in terms of r, s and t : s=2x+t/r
Anna007 [38]

For this case we have the following equation:

s = \frac {2x + t} {r}

We must clear the value of the variable "x" as a function of r, s and t:

If we multiply by "r" on both sides of the equation we have:

rs =2x + t

If we subtract "t" on both sides of the equation we have:

rs-t = 2x

If we divide by "2" on both sides of the equation we have:

x = \frac {rs-t} {2}

Thus, the value of the variable "x" is:

x = \frac {rs-t} {2}

Answer:

x = \frac {rs-t} {2}
