Use the distributive property to simply the expression below.
2 (4b-6)

The answer is 8b-12

Step-by-step explanation:

When using the distributive property you must expand the equation.

First you distribute the 2 to the 4b by multiplication: 2 x 4b = 8b

Second you distribute the 2 to the -6 by multiplication: 2 x (-6) = -12

Finally you combine your 2 expressions and result with the new distributed equation of: 8b-12

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

$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
