Answer:

L=4W-2

P=2L+2W

36= 2(4W-2)+2W

36= 8W-4 +2W

36= 10W-4

36+4=10W

40=10W

40/10=W

W=4

L=4(4)-2

L=14

AREA =L(W)

AREA = 4X14

AREA =48 cm

Solve the compound inequality 6b < 36 or 2b + 12 > 6.
Ne4ueva [31]

The solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

<h3>How to solve the compound inequality?</h3>

The compound inequality is given as:

6b < 36 or 2b + 12 > 6

Evaluate the like terms in the individual inequalities

6b < 36 or 2b > -6

Divide the individual inequalities by the coefficients of b

b < 6 or b > -3

Hence, the solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3
