We can split this figure up into two shapes - a rectangle and a triangle.

The rectangle has a width of 9 cm and a length of 12 cm. The triangle has a height of 15 - 9 = 6 cm and a base length of 12 - 3 - 3 = 6 cm.

Rectangle:

A = 12 x 9

A = 108 cm^2

Triangle:

A = 1/2 x 6 x 6

A = 1/2 x 36

A = 18 cm^2

Total figure:

108+ 18 = 126

The area of the figure is 126 cm^2.

Hope this helps!! :)

Two decimals numbers, to the thousandths, that have a sum of about 5 and a difference of about 3. Then do the math to prove it w

mina [271]

Answer:

The numbers are approximately: 4.000 and 1.000

Step-by-step explanation:

The given parameters can be expressed as:

$\frac{x}{1000} + \frac{y}{1000} \approx 5$

$\frac{x}{1000} - \frac{y}{1000} \approx 3$

Required

Determine the numbers

In each of the equations, multiply by 1000

$1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5]$

$x + y \approx 5000$

$1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3]$

$x-y \approx 3000$

So, we have:

$x + y \approx 5000$

$x-y \approx 3000$

Add the two equations

$x + x + y - y \approx 5000 + 3000$

$2x \approx 8000$

Solve for x

$x \approx 8000/2$

$x \approx 4000$

Substitute $x \approx 4000$ in $x + y \approx 5000$

$4000 + y \approx 5000$

$y \approx 5000 - 4000$

$y \approx 1000$

Using:

$\frac{x}{1000} + \frac{y}{1000} \approx 5$

We have:

$\frac{4000}{1000} + \frac{1000}{1000} \approx 5$

$4.000 + 1.000 \approx5$

<em>This implies that, the numbers approximates to 4.000 and 1.000, respectively.</em>

A line point has its end points at -9 and 6. find the coordinate of the midpoint of the segement

Ivahew [28]

The midpoint of A = a i B = b: $\dfrac{a+b}{2}$

A = -9; B = 6

$\dfrac{-9+6}{2}=\dfrac{-3}{2}=-1.5$
