S = 2lw + 2wh + 2lh; solve for l

Pavel [41]

Answer:

l = (S - 2wh)/(2w + 2h)

Step-by-step explanation:

S = 2lw + 2wh + 2hl

S - 2wh = 2lw + 2hl

S - 2wh = l (2w + 2h)

(S - 2wh)/(2w + 2h) = l

PRECALCULUS HONORS HELP ME PLZ AND THANKS

Inequalities are used to show the relationship between unequal expressions

The set notation of (5) and (6) are: $\{x : -6 > x \ge -2\}$ and $\{x:-4 < x \ge 6\}$ .
See attachment for the graphs

The following should be notated when plotting the graph of an inequality

< and > are represented with open circles, while $\leq$ and $\geq$ are represented with closed circles
The arrows of and $\le$ point to the left, while the arrows of $>$ and $\geq$ point to the right.

So, we have:

$(a)\ -8 < x$

Rewrite as:

$x > -8$

The graph of $x > -8$ will point to the right, and it will use an open circle

$(b)\ -6 > x \ge -2$

Split the inequality:

$-6 > x$ and $x \ge -2$

It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.

Hence. $-6 > x \ge -2$ cannot be represented on a graph

$(c)\ -4$

Split the inequality:

$-4 < x$ and $x \ge 6$

$-4 < x$ means that -4 is less than x or x is greater than -4.

So, we have:

$x > -4$ and $x \ge 6$

If $x > -4$ and $x \ge 6$ , then we make use of $x > -4$ because it contains more values of x.

The graph of $x > -4$ will point to the right, and it will use an open circle
