Answer:

Step-by-step explanation:

break it into pieces



put it all together
*since there's no negative in front of the other numbers except 7 they're positive so you add them*

simplify

Answer: See below
Explanation:
(x^2+10x+7)(2x-1) = 2x^3+19x^2+4x-7
2x^3-x^2+20x^2-10x+14x-7 = 2x^3+19x^2+4x-7
2x^3+19x^2+4x-7 = 2x^3+19x^2+4x-7

Part (a)
The angles would stay the same. This is because similar figures keep the same shape, but the size will shrink or grow.
A real world application is to simply move your head closer to the page and the figure will appear to get larger. The angles themselves stay the same but the side lengths will get larger.
====================================================
Part (b)
While the angles stay the same under a dilation operation, the side lengths do not. As the instructions state: "The side lengths are 3 times longer" (paraphrased).
So we multiply each side length in the diagram by 3
- DE = 3*JK = 3*4.5 = 13.5
- EF = 3*KL = 3*3 = 9
- FG = 3*LM = 3*2 = 6
- GD = 3*MJ = 3*2.5 = 7.5
Refer to the diagram below. I've used the resize feature to enlarge the image to make figure DEFG
A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
