a 3x^2+18
b3x+3
c3x+9
d3x+5


2nd question.
Find the area of the given triangle.
a 2x^2+5x+12
b x^2+5x+6
c 2x^2+10x+12

Answer 1

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
