Answer:
1.we know the perimeter of the triangle=x-3+x+6+x=3x+3
so,answer is (b)3x+3
2.area of the triangle=1/2*b*h
=1/2*x+2*2x+6=x+2*2x+6/2=2x^2+6x+4x+12/2=2x^2+10x+12/2=2(x^2+5x+6)/2=x^2+5x+6
so,answer is(b)x^2+5x+6
no because the three is negative so the -3 is less than c.
Hope this helps.
Answer:
n=14/9
Step-by-step explanation:
3/4n+2/3=11/6
3/4n=11/6-2/3
3/4n=11/6-4/6
3/4n=7/6
n=(7/6)/(3/4)
n=(7/6)(4/3)
n=28/18
simplify
n=14/9
