L = longer piece s = shorter piece
{ l + s = 63
{ l = s + 15
l + s = 63
(s + 15) + s = 63
2s = 63 - 15
2s = 48
s = 48
2
s = 24
l + s = 63
l + 24 = 63
l = 63 - 24
l = 39

Answer:
r=-2/3 or r= 6
Step-by-step explanation:
To solve this equation to find r, first subtract 5 from both sides.
3r² - 16r -7 -5= 5 -5
3r² - 16r -12= 0 (simplify)
(3r + 2)(r - 6)= 0 (factorise the equation)
3r+2=0 or r-6=0
3r= -2 or r= 6
r= -2/3
