Answer: -8
Step-by-step explanation:
Distribute -0.95 so that the equation will become 1.9= -0.95b - 5.7
Add 5.7 on both sides so that the equation becomes 7.6= -0.95b
Divide -0.95 on both sides
The answer will be -8.
Answer:
1. The pin’s location aids to create two drawings simultaneously. This is that while drawing an image, a copy, which may vary in size, is created at the same time.
2. The pantograph relates to dilation and similarity due to the use of similar triangles that affect the scale of the second drawing.
3. The use of similar triangles illustrates the process of the pantograph because the ratio of similitude is set when determining where to place the pin. When a triangle is moved while tracing a line, along with the outline of the image, an enlarged/reduced version of the image is created by the other pantograph's end.
4. The pantograph is now obsolete and has been replaced by several different ways of producing duplicates such as photocopying, mass printing, and digital filing.
Answer:
The second option
Step-by-step explanation:
The second option is correct because the base of the triangle, which is 3 cm, plus the base of the rectangle, which is 5 cm, is equal to the base of the trapezoid, which is 8 cm.
Hope this helps! :)

Answer:
It's 8x²+8x-6
Step-by-step explanation:
If you multiply each component you get:
4x * 2x = 8x²
4x * 3 = 12x
-2 * 2x = -4x
-2 * 3 = -6
Adding everything you have the result.
