The technology company asks the general contractor to lay gravel on the ground in the area between the warehouse and the fence. Which of the following situations best models the area that the gravel will cover? (Multiple answers) A = (6 x feet)(6 x feet) - (15 x feet)(8 x feet)
A = 84 x2 feet 2
A = (15 x feet)(8 x feet) - (6 x feet)(6 x feet)
None of the above.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

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

16 is the absolute value
