What are the dimensions of the rectangle shown below? Remember to use the axes on the coordinate grid to help you. A coordinate grid is shown with scale from negative 14 to 0 to positive 14 on both x- and y-axes at increments of 2. A figure ABCD is shown with A at ordered pair negative 8, 2, B at ordered pair 8, 2, C at ordered pair 8, negative 6, and D at ordered pair negative 8, negative 6.

14 units × 4 units
16 units × 8 units
24 units × 14 units
64 units × 4 units

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

answer: 800
