Answer:

C  459cm2

Step-by-step explanation:

You multiply the area of the square first and add that to the area of the two right triangles.

<u>Area of the square</u> - Bh = 22(18) = 396

<u>Area of ONE right triangle</u> - 1/2bh    h = 7    b = the base of the triangle

Look at the bottom of the square (18 cm) and divide that by two to get the base of the triangle

1/2(9)(7) = 31.5

<u>Area of BOTH right triangles </u>- 31.5(2) = 63

<u>Total Area</u> - Then you add 396 to 63 and you get 459 cm2, or C, which is the answer

An interior angle of a regular polygon has a measure of 135° how many sides does it have
butalik [34]

8 sides

the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )

the sum of the exterior angles of a polygon = 360°

number of sides = \frac{360}{45} = 8

Which graph shows the solution to this system of inequalities?<br> y&gt;-1/3x+1<br> y&gt;2x-3
Mademuasel [1]

Given:

The system of inequalities is:

y>-\dfrac{1}{3}x+1

y>2x-3

To find:

The graph of the given system of inequalities.

Solution:

We have,

y>-\dfrac{1}{3}x+1

y>2x-3

The related equations are:

y=-\dfrac{1}{3}x+1

y=2x-3

Table of values for the given equations is:

    x                   y=-\dfrac{1}{3}x+1             y=2x-3

   0                             1                              -3

   3                             0                              3

Plot (0,1) and (3,0) and connect them by a straight line to get the graph of y=-\dfrac{1}{3}x+1.

Similarly, plot (0,-3) and (3,3) and connect them by a straight line to get the graph of y=2x-3.

The signs of both inequalities are ">". So, the boundary line is a dotted line and the shaded region or each inequality lie above the boundary line.

Therefore, the graph of the given system of inequalities is shown below.
