The remaining area of the paperboard is 363 square inches.

Step-by-step explanation:

The length of the rectangular board = 26 inches

The width of the rectangular board = 20 inches.

Now, the area of the board = $26\times20=520$ square inches

Now, a semicircle has been cut out of it.

Let is assume that the diameter of the semicircle be 20 inches.

So, radius will be = 10 inches

Area of semicircle is = $\frac{1}{2} \pi r{2}$

So, we get : Area = $\frac{1}{2}\times3.14\times10\times10$

= 157 square inches.

Now after cutting the semi circle, the area remained = 520-157=363 square inches.

Therefore, the remaining area of the paperboard is 363 square inches.

Answer from: Quest

$x=-2$ or $x=-5$

step-by-step explanation:

we need to solve for 'x' the following equation: $\sqrt{(x+6)} - 4 = x$

we have that:

$\sqrt{(x+6)} - 4 = x$ ⇒ $(x+6) = (x+4)^{2}$

⇒ $x+6 = x^{2} + 8x + 16$ ⇒ $x^{2} + 7x + 10 = 0$

factorizing, we get that:

$x^{2} + 7x + 10 = 0$ ⇒ $(x+2)(x+5)=0$

then, the solutions are: $x=-2$ or $x=-5$

nothing extraneous has been found!
