Mathematics: Ineed with this because i don’t get it so if you can me let me know

You should use photomath it is an app that can answer any equations and the answer will tell you where to mark it in the graph :) example: if the answer is 17.5 you would mark a dot between 17 and 18 !!...

Mathematics

Step-by-step explanation:

(1)

$\triangle ACD$ has the constant ratio of the sides. AB/AC = AE/ED

So solving for x is simple:

AB/AC = 6/2 = 3 = AE/x = 9/x

9/x = 3

9 = 3x

x = 3

(2)

$\triangle GIF$ is similar to $\triangle IJH$

To be similar, the ratio between the respective sides must be equal =>

IJ/IF = IH/IG = HJ/GF.

So we plug in the value of the sides.

10/5 = x/12

x/12 = 10/5

x/12 = 2

x = 24

(3)

I don't understand the picture (Sorry)

(4)

$\triangle RPS[\tex] is similar to [tex]\triangle QPT$

Which implies:

PQ/QR = QT/RS

5/7 = 4/x

[4/x = 5/7] * x

4 = (5/7)x

x = 4 * 7/5 = 28/5 = 5 3/5
