Assuming that we are solving in terms of n.
Start by distributing:
2(n + 5)
(2*n) + (5*2)
2n + 10 = -2
Subtract 10 to start toward isolating your variable:
2n = -12
Divide by two to finish solving:
n = -6
Hmm I’ve done this before but I can’t remember sorry but I will try and think
Equilateral
Isosceles
Scalene
Right
Acute
Obtuse
B you can tell just by look x^2*x^2=x^4
