Answer:

152 shaded squares

Step-by-step explanation:

The first square has 12 shaded blocks, the second square has 16, the third box has 20 shaded blocks so I know that the shaded box's are increasing by 4 each figure and the first box starts with 12. So I multiplied 4 by 35 and got 140 I then add the 12 that figure 1 started with and got 152. So the 35th box has 152 shaded squares.

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly?

Aneli [31]

Answer:

The required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .

Step-by-step explanation:

If a quadratic equation is $ax^2+bx+c=0$ , then the quadratic formula is

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is

$x^2-9x-20=0$

Here, a=1, b=-9 and c=-20.

Substitute a=1, b=-9 and c=-20 in the above quadratic formula.

$x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$

Therefore the required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .
