Rickey has been commissioned to paint a mural that is allowed to have an area of 50 square meters. To make the rectangle shape o

Leno4ka [110]

Answer:

12.808 meter is the length should Rickey use for the mural.

Step-by-step explanation:

Area of the mural = A = $50 m^2$

Length of the mural = l

Width of the mural = w

l = 5 + 2w

Area of the rectangle = l × w

$A=(5+2w)\times w$

$50 m^2=5w+2w^2$

$2w^2+5w-50=0$

Solving above equation with the help of Completing squares method:

$(\sqrt{2}w)^2+2\times \sqrt{2}w\times \frac{5}{2\sqrt{2}}+(\frac{5}{2\sqrt{2}})^2-50=(\frac{5}{2\sqrt{2}})^2$

$(a+b)^2=a^2+b^2+2ab$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=(\frac{5}{2\sqrt{2}})^2+50$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=\frac{25}{8}+50$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=\frac{425}{8}$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})=\pm\sqrt{\frac{425}{8}}$

w = 3.904 m (accept)

w = -6.404 m (reject)

l = (5 + 2w)m = 5 + 2 × (3.904) m= 12.808 m

12.808 meter is the length should Rickey use for the mural.

Answer:

see below

Step-by-step explanation:

When in doubt, you can always multiply them out to see .

The expression a^6 + b^6 can be treated as the sum of cubes, which factors as ...

p^3 + q^3 = (p +q)(p^2 -pq +q^2)

In this case, you have p=a^2 and q=b^2, so the factorization is ...

a^6 +b^6 = (a^2 +b^2)((a^2)^2 -(a^2)(b^2) +(b^2)^2)

a^6 +b^6 = (a^2 +b^2)(a^4 -a^2b^2 +b^4) . . . . . . matches choice D

The expression a^6 -b^6 can be treated either as the difference of cubes, or as the difference of squares. In the former case, its factorization would be ...

a^6 -b^6 = (a^2 -b^2)(a^4 +a^2b^2 +b^4) . . . . . . matches no offering

In the latter case, its factorization could be any of ...

a^6 -b^6 = (a^3 -b^3)(a^3 +b^3)

a^6 -b^6 = (a^3 -b^3)(a +b)(a^2 -ab +b^2) . . . . . . . . . . . matches no offering

a^6 -b^6 = (a -b)(a^2 +ab +b^2)(a +b)(a^2 -ab +b^2) . . . matches no offering

a^6 -b^6 = (a^2 -b^2)(a^2 +ab +b^2)(a^2 -ab +b^2) . . . matches no offering
