Area of the figure=area of the square - area of the rectangle 1 - area of the rectangle 2.

Area of the square=side x side=12 * 12 =144
Area of the rectangle 1=8 *5=40
Area of the rectangle 2=5 * (12-8)= 5 * 4=20

Area of the figure=144 - 40 -20=84

Answer : 84

Well, the formula to find the area of something is base times height, so you'll have to multiply the base and height at the bottom, which is 12 times 12 which is 144, and then find the area of the missing/cut-out piece which is 8 times 5 which will be 40, and then subtract the two areas, (144 - 40), which will give you your final area of 104 square inches.
I hope I helped! =D

Answer:

The factors of  2(x+y)^2-9(x+y)-5 is ((x+y)-5)(2x+2y+1)

Step-by-step explanation:

Given polynomial

=>2(x+y)^2-9(x+y)-5

To Find:

The factors of the polynomial =?

Solution:

Lets assume  k = (x+y)

Then 2(x+y)^2-9(x+y)-5 can be written as 2k^2-9k-5

Now by using quadratic formula

k =\frac{-b\pm\sqrt{(b^2-4ac}}{2a}

where

a= 2

b= -9

c= -5

Substituting the values, we get

k =\frac{-b\pm\sqrt{(b^2-4ac)}}{2a}

k =\frac{-(-9) \pm \sqrt{((-9)^2-4(2)(-5)}}{2(2))}

k =\frac{-(-9) \pm \sqrt{(81+40)}}{4}

k =\frac{-(-9) \pm \sqrt{(121)}}{4}

k =\frac{-(-9) \pm 11}}{4}

k= \frac{ 9 \pm 11}{4}

k =  \frac{20}{4}                         k =  \frac{-2}{4}    

k_1 =5                                      k_2 = -\frac{1}{2}

2k^2-9k-5= 2(k-5)(k+\frac{1}{2})

Solving the RHS we get

\frac{2}{2}(k-5)(2k+1)

(k-5)(2k+1)

Substituting k = x+y

((x+y)-5)(2(x+y+1)

((x+y)-5)(2x+2y+1)
