The area in square inches, of the shaded part of the image below is: (Enter only a number as your answer.)

92

Step-by-step explanation:

Area of this figure =(BC times AB) - (HE times HG)

Line segment BC= 12

Line segment AB=9

12 times 9 = 108

108- (HE times HG)

HE= AD - AH - ED

AD = 12

AH = 4

ED = 4

HE= 12-4-4

HE=4

HG= 4

HE times HG = 16

108- 16 = 92

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
