Will give brainliest lots of points A is the midpoint of LB,Lb =6x-17 and AB=2x+3

NARA [144]

A is the mid point ==> AL = AB = 2AB
6x-17=2(2x+3) => 6x -17 = 4x +6 => 2x = 23 =>x=23/2
then just plug x into LB and AB

(b2) what's the missing exponent = b−10

amid [387]

According to the given expression, the value of b if $b^2=b^{-10}\\$ is -1 and + 1

Indices are expressed using exponents and bases. Some of the useful laws of indices are:

$a^m\times a^n=a^{m+n}\\a^{-n}=\frac{1}{a^n}$

Given the expression;

$b^2=b^{-10}\\$

This can also be expressed as:

$b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1$

Hence the value of b from the given indices is -1 and + 1
