-138 <span>≥ -6(6b - 7)

Start by multiplying everything within the parentheses by -6.

-138 </span><span>≥ -36b + 42

Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)

-138 - 42 </span><span>≥ -36b

-180 </span>≥ -36b

Divide both sides by -36 to find the value of b.

-180 / -36 ≥ b

5 ≥ b.

The answer is b ≤ 5.

Given a rectangle with a perimeter of 24 inches, why dimensions maximize the area?
Pepsi [2]

Answer:

The dimensions are 6 by 6

Step-by-step explanation:

Calculus answer:

2x +2y= 24

xy= A

2x=24-2y

x=12-y

(12-y)(y)= 12y- y^2

the Derivative is = 12-2y

Then set that equal to zero 0=12-2y

-12=-2y

y=6

Confirm that 6 is a maximum by using a wiggle graph

wiggle graph -∞<---inc--6---dec-->∞

6 is a maximum

plug into original equation

2x + 2(6)=24

2x+12=24

2x=12

x=6

----------------------------------------------------------------------------------------------------

y=6

x=6
