Answer:

Step-by-step explanation:

18y -30 -7y =25

solution

18y -30 -7y =25

so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue

18y -7y=25+30

when a negative is crossing an equal sign it turns positive and vice versa

so lets solve

11y=55

the one with the unknown will divide

11y/11=y

you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc

Then 55/11=5

so y=5

Thats the correct answer....

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
