The number of smaller triangles along one side of the larger triangle is the square root of the total number of triangles. The perimeter of the large triangle is ... 3*(2 cm)*√121 = 66 cm
Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0) then 0 =4x^2 -12x + 9 0=(2x-3)(2x-3) 0=2x-3 so x=3/2 that is x-intercept
