{ 2 x [4 - (6 ÷ 2)]} x 3

bracket first (6÷2)=3

[4-3]=1

{2×1}=2

then you multiple 3 by 2 since after solving what is in the bracket,the answer was 2

3×2=6 BODMASS much be applied

the answer is z7+8/5

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
