Answer:
x = -10
Step-by-step explanation:
Combine like terms and solve for x
3x + 8 = x - 12
3x= x - 20
2x = -20
x = -10
Hello :
2x²-10 = 2(x-0)²-10 <span>in vertex form</span>
The expression represents the possible values of n, in feet
x-1<n<3x+5
If a, b and c are the lengths of the triangle's sides, then
a+b>c
a+c>b
b+c>a
Since,a=2x+2
b=x+3
z=n
2x+2+x+3>n
n<3x+5
2x+2+n>x+3=2x+2
n>x-1
Therefore the simplest form of the answer is x-1<n<3x+5.
