Can someone help me with this

Mathematics
1 answer:
Oksanka [162]3 years ago
7 0

Answer:

20

Step-by-step explanation:

We know that the formula for the area of something is 1/2 * base * height

So we multiply 1/2 * 8 * 2 for The first triangle and get 8

Repeat for the other 3:

1/2* 2*2 = 2

8+8+2+2 = 20

* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.

I hope this helps :)

What is the sum of the first 39 positive odd numbers?
liq [111]
1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.

Help Pleasee<br><br> Reflect shape A in the line x = -2
Cerrena [4.2K]

Answer: Check out the diagram below

The reflected image is shown in red.

=================================================

Explanation:

Draw a vertical line through -2 on the x axis. This is the mirror line.

Now focus on the upper right corner of the figure, which is at (-3, -1). Notice how the horizontal distance from this corner point to the mirror line is exactly 1 unit. If we move another 1 unit to the right, then we'll arrive at (-1,-1) which is where the reflected point lands or ends up.

In short, the upper right corner point (-3,-1) reflects over x = -2 to land on (-1,-1)

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

As another example, the upper left corner point (-5, -1) will move exactly 4 spaces to the right to get to the mirror line. Then we move another 4 spaces to the right to get to (2,-1).

So the upper left corner (-5,-1) will ultimately move to (2,-1) after the reflection over x = -2.

Apply these steps to the other corner points and you'll end up with what is shown below.

Take note that a point like A(-5,-1) moves to A'(1,-1), and similar to the other points as well. Also, notice that when going from A to B to C, etc we are moving clockwise. We move counterclockwise when going from A' to B' to C' etc. Reflections always swap the orientation.
