3.1 Solve<span> : </span>4x2<span>+3 = 0. Subtract 3 from both sides of the equation : </span><span>4x2 = -3</span>. Divide both sides of the equation by 4: x2<span> = -3</span>/4 = -0.750. When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: x = ± √ -3/4. In Math, i is called the imaginary unit. It satisfies i 2<span> =-1.</span>
Answer:68
Step-by-step explanation:
angle sum property
56+y+y-12=180
44+2y=180
2y=180-44=136
y=136/2
=68
VERIFICATION :56+68+56
=180
<span> The Pythagorean theorem</span>
