What is the area of this polygon? Enter your answer in the box. units²

Gemiola [76]

Answer:

The area of the polygon is $39\:units^2$

Step-by-step explanation:

Sketch the polygon to obtain the figure in the attachment.

The polygon can then be divided into a rectangle and a triangle.

The area of the polygon

$=|VE|\times |DE|+\frac{1}{2}\times |DE|\times |AM|$

We use the absolute value method to find the lengths

$=|3--2|\times |3--3|+\frac{1}{2}\times|3--3|\times |5-2|$

$=5\times 6+\frac{1}{2}\times 6\times 2$

$=30+9$

$=39\:units^2$

Solve the system of inequalities: a) .4x−1≤0 2.3x≥4.6

OleMash [197]

Answer:

(a) $x \leq 2.5$

(b) $x \geq 2$

Step-by-step explanation:

Solving (a):

$0.4x - 1 \leq 0$

Add 1 to both sides

$0.4x - 1 + 1\leq 0 + 1$

$0.4x \leq 1$

Solve for x

$x \leq 1/0.4$

$x \leq 2.5$

Solving (b):

$2.3x \geq 4.6$

Solve for x

$x \geq 4.6/2.3$

$x \geq 2$
