The area of a parallelogram is 31.5 ft2 and the height is 6.3 ft. What is the length of the base?

the correct answer is 45x

9×5=45 then add the x

she drove 134 miles

step-by-step explanation:

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
