2) Qual dos polinômios a seguir não foi desenvolvido corretamente? ○(x+5)²=x²+10x+25
○(x-6)(x+6)=x²+36
○(x-2)²=x²-4x+4
○(x-1)(x+3)=x²+3x-3
○(a-b)(a+b)=a²-b²

it is 10.6 according to my calculations

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
