Answer:

41 square miles

Step-by-step explanation:

There are several ways you can compute the area of this polygon. We have elected to divide it into a rectangle and a triangle.

The rectangle has dimensions 8 × 4.5, so area ...

A = LW = 8 × 4.5 = 36 . . . . . square miles

The triangle has height 2.5 and base 4, so area ...

A = (1/2)bh = (1/2)(4)(2.5) = 5 . . . . . square miles

Then the total area is the sum of these:

36 + 5 = 41 . . . . . square miles

What equation results from completing the square and then factoring? x^2+22x=31 A.(x+22)^2=53 B.(x+22)^2=152 C.(x+11)^2=152 D.(x

Paladinen [302]

Answer:

$\boxed{\mathrm{Option \ C}}$

Step-by-step explanation:

=> $x^2+22x = 31$

=> $(x)^2+2(x)(11) = 31$

Since b = 11 , So $(11)^2$ needs to be added to both sides

Adding $(11)^2$ to both sides

=> $(x)^2+2(x)(11)+(11)^2 = 31+(11)^2$

Completing the square

=> $(x+11)^2 = 31+121$

=> $(x+11)^2 = 152$
