Evaluate ab-0.5bab-0.5ba minus 0 point 5,b when a=1a=1a equals 1 and b=5b=5

Step-by-step explanation:

We want to evaluate when a=1 and b=5.

We just have to substitute the value of a and b into the given expression and simplify.

This simplifies to:

This will finally give us;

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
