Use simultaneous equations.
let the number of bracelets be y and necklaces be z.
so
2y + 3z = 95. this is formula 1
y + z = 37. this is formula 2
so from formula 2, we can change that to
y = 37 - z. this is formula 3
sub 3 into 1,
2 (37-z) + 3z = 95
74 - 2z + 3z = 95
z = 21
sub z = 21 into 3,
y = 37 - 21
y = 16
therefore you sold 16 bracelets and 21 necklaces
The center-radius form is: (x−h)^2+(y−k)^2=r^2
Knowing this, all we need to do is square root the 64 to get 8 as your radius.
Using the distributive property, we have -12w^2-2w since a(b+c)=ab+ac
Hope this helped
