X^2 - 47 = 0
this cannot be factroed
Add 47 to both sides and take the square roots:-
x^2 = 47
x = +/- sqrt47
Its B
Answer:
First graph is y = 2x +5 (you can tell by the intercept)
Second graph is y = -x + 1 (you can tell because it has a negative slope)
Third graph is y= 1/5x -2 (last option left, and you can tell by the intercept)
Triangle ABC is similar to triangle DEF because all triangles have 180 degrees. When you subtract 180 by 30, you get 150. When you subtract 150 by 6<span>4</span>, you get 86. Therefore, the triangles are the same.
7(q - 74) = 84
7q - 518 = 84
